Abstract
The OPERA experiment is based on a hybrid technology combining electronic detectors (EDs) and nuclear emulsions. OPERA collected muonneutrino interactions during the 2008 and 2009 physics runs of the CNGS neutrino beam, produced at CERN with an energy range of about 535GeV. A total of 5.31019 protons on target equivalent luminosity have been analysed with the OPERA EDs: scintillator strips target trackers and magnetic muon spectrometers equipped with resistive plate gas chambers and drift tubes, allowing a detailed reconstruction of muonneutrino interactions. Charged current (CC) and neutral current (NC) interactions are identified, using the measurements in the EDs, and the NC/CC ratio is computed. The momentum distribution and the charge of the muon tracks produced in CC interactions are analysed. Calorimetric measurements of the visible energy are performed for both the CC and NC samples. For CC events, the Bjorken-y distribution and the hadronic shower profile are computed. The results are compared with a detailed Monte Carlo simulation of the response of EDs.

OPERA collected muonneutrino interactions during the 2008 and 2009 physics runs of the CNGS neutrino beam, produced at CERN with an energy range of about 535GeV. A total of 5.31019 protons on target equivalent luminosity have been analysed with the OPERA EDs: scintillator strips target trackers and magnetic muon spectrometers equipped with resistive plate gas chambers and drift tubes, allowing a detailed reconstruction of muonneutrino interactions. Charged current (CC) and neutral current (NC) interactions are identified, using the measurements in the EDs, and the NC/CC ratio is computed. The momentum distribution and the charge of the muon tracks produced in CC interactions are analysed. Calorimetric measurements of the visible energy are performed for both the CC and NC samples. For CC events, the Bjorken-y distribution and the hadronic shower profile are computed. The results are compared with a detailed Monte Carlo simulation of the response of EDs.</div></front></TEI><istex><corpusName>iop</corpusName><author><json:item><name>N

detectors (EDs) and nuclear emulsions. OPERA collected muonneutrino interactions during the 2008 and 2009 physics runs of the CNGS neutrino beam, produced at CERN with an energy range of about 535GeV. A total of 5.31019 protons on target equivalent luminosity have been analysed with the OPERA EDs: scintillator strips target trackers and magnetic muon spectrometers equipped with resistive plate gas chambers and drift tubes, allowing a detailed reconstruction of muonneutrino interactions. Charged current (CC) and neutral current (NC) interactions are identified, using the measurements in the EDs, and the NC/CC ratio is computed. The momentum distribution and the charge of the muon tracks produced in CC interactions are analysed. Calorimetric measurements of the visible energy are performed for both the CC and NC samples. For CC events, the Bjorken-y distribution and the hadronic shower profile are computed. The results are compared with a detailed Monte Carlo simulation of the response of EDs.</abstract><qualityIndicators><score>7.456</score><pdfVersion>1.4</pdfVersion><pdfPageSize>595.276 x 841.89 pts

OPERA collected muonneutrino interactions during the 2008 and 2009 physics runs of the CNGS neutrino beam, produced at CERN with an energy range of about 535GeV. A total of 5.31019 protons on target equivalent luminosity have been analysed with the OPERA EDs: scintillator strips target trackers and magnetic muon spectrometers equipped with resistive plate gas chambers and drift tubes, allowing a detailed reconstruction of muonneutrino interactions. Charged current (CC) and neutral current (NC) interactions are identified, using the measurements in the EDs, and the NC/CC ratio is computed. The momentum distribution and the charge of the muon tracks produced in CC interactions are analysed. Calorimetric measurements of the visible energy are performed for both the CC and NC samples. For CC events, the Bjorken-y distribution and the hadronic shower profile are computed. The results are compared with a detailed Monte Carlo simulation of the response of EDs.</p></abstract></profileDesc><revisionDesc><change when="2011">Published</change></revisionDesc></teiHeader></istex:fulltextTEI><json:item><original>false</original><mimetype>text/plain</mimetype><extension>txt</extension><uri>https://api.istex.fr/document/62EB70770E9363BC903BCE989F944B99E287E2BC/fulltext/txt</uri></json:item></fulltext><metadata><istex:metadataXml wicri:clean="corpus iop not found" wicri:toSee="no header"><istex:xmlDeclaration>version="1.0" encoding="ISO-8859-1" </istex:xmlDeclaration><istex:docType SYSTEM="http://ej.iop.org/dtd/iopv1_5_2.dtd" name="istex:docType"></istex:docType><istex:document><article artid="nj384249"><article-metadata><jnl-data jnlid="nj"><jnl-fullname>New Journal of Physics</jnl-fullname><jnl-abbreviation>New J.

OPERA collected muon–neutrino interactions during the 2008 and 2009 physics runs of the CNGS neutrino beam, produced at CERN with an energy range of about 5–35 GeV. A total of <inline-eqn><math-text>5.3×10<sup>19</sup></math-text></inline-eqn> protons on target equivalent luminosity have been analysed with the OPERA EDs: scintillator strips target trackers and magnetic muon spectrometers equipped with resistive plate gas chambers and drift tubes, allowing a detailed reconstruction of muon–neutrino interactions. Charged current (CC) and neutral current (NC) interactions are identified, using the measurements in the EDs, and the NC/CC ratio is computed. The momentum distribution and the charge of the muon tracks produced in CC interactions are analysed. Calorimetric measurements of the visible energy are performed for both the CC and NC samples. For CC events, the Bjorken-<inline-eqn><math-text><italic>y</italic></math-text></inline-eqn> distribution and the hadronic shower profile are computed. The results are compared with a detailed Monte Carlo simulation of the response of EDs.</p></abstract></abstract-group></header><body refstyle="numeric"><sec-level1 id="nj384249s1" label="1"><heading>Introduction</heading><p indent="no">OPERA [<cite linkend="nj384249bib1">1</cite>] is a hybrid experiment based on electronic detectors (EDs) and nuclear emulsions. It is exposed to the long-baseline CNGS beam [<cite linkend="nj384249bib2">2</cite>] from CERN to the Gran Sasso underground laboratory (LNGS) 730 km away from the neutrino source. The main purpose of the experiment is the observation of <inline-eqn><math-text>ν<sub>μ</sub></math-text></inline-eqn> to <inline-eqn><math-text>ν<sub>τ</sub></math-text></inline-eqn> oscillations in the direct appearance mode. The <inline-eqn><math-text>ν<sub>τ</sub></math-text></inline-eqn> are identified through the measurement of the <inline-eqn><math-text>τ</math-text></inline-eqn> leptons produced in their charged current (CC) interactions. The neutrino runs started in 2008 and a first <inline-eqn><math-text>ν<sub>τ</sub></math-text></inline-eqn> candidate has recently been observed [<cite linkend="nj384249bib3">3</cite>].

CC and neutral current (NC) interaction measurements are then discussed. The NC-to-CC ratio, the muon momentum spectrum, the reconstructed energy and the hadronic shower profile are investigated and a detailed comparison with an MC simulation is presented.

Each spectrometer consists of a dipolar magnet with two arms made of 12 iron plates; the measured magnetic field strength is 1.52 T. The two arms are interleaved with six vertical drift-tube planes, the precision trackers (PTs), for the precise measurement of the bending of the muon tracks.

These planes provide a coarse tracking, a range measurement of the stopping particles and a calorimetric analysis of the hadrons escaping the target along the incoming neutrino direction. Two planes of resistive plate chambers (XPC), with the readout strips tilted by <inline-eqn><math-text>±42.6°</math-text></inline-eqn> with respect to the horizontal, are also placed after each target section to solve left/right ambiguities in the track pattern recognition.

In the QE and RES processes, the hadronic system observable in the detector is faint as most of the incoming neutrino energy is transferred to the final state lepton. Conversely, in the DIS process, a prominent hadronic system is observed in the detector. In order to obtain a prediction for the number of expected neutrino interactions in OPERA, the differential neutrino cross sections, <inline-eqn><math-text><upright>d</upright>σ/<upright>d</upright><italic>E</italic></math-text></inline-eqn>, for the CC-DIS, CC-QE and CC-RES processes on an isoscalar target, known from other experiments [<cite linkend="nj384249bib7">7</cite>], are convoluted with the CNGS neutrino flux. The mean energy of the incoming beam is 17.7 GeV [<cite linkend="nj384249bib8">8</cite>] if the long tail extending above 100 GeV is not included. Only 0.6% of the total flux has an energy exceeding 100 GeV; this corresponds to less than 4% of the <inline-eqn><math-text>ν<sub>μ</sub></math-text></inline-eqn> CC event rate on an isoscalar target [<cite linkend="nj384249bib2">2</cite>]. Once the detector target mass and the number of recorded p.o.t. are defined, the absolute prediction for the expected number of interactions is computed together with the relative fractions of each process. The CC-DIS, CC-QE and CC-RES fractions are corrected for the non-isoscalarity of the materials used in the OPERA detector. The CC-DIS process is found to be dominant with a fraction exceeding 90%. Using the procedure outlined in [<cite linkend="nj384249bib7">7</cite>], the NC-to-CC ratio on an isoscalar target is predicted to be 0.31, while it is 0.29 once the non-isoscalarity corrections are taken into account. Hence, the NC contribution is also fixed. Only NC interactions in the DIS regime are considered as final state particles have to be observed in the EDs. The final states for the different processes, CC-DIS, CC-QE, CC-RES and NC-DIS, are generated using NEG MC program [<cite linkend="nj384249bib9">9</cite>], developed in the framework of the NOMAD experiment [<cite linkend="nj384249bib10">10</cite>]. NEG MC is supplied with the CNGS neutrino spectrum up to 400 GeV. The generated events can then be mixed according to the appropriate fractions.</p></sec-level2><sec-level2 id="nj384249s3.2" label="3.2"><heading>Environment simulation of the OPERA detector</heading><p indent="no">For the event simulation in the target, neutrino interaction primary vertexes are generated in the lead/emulsion volumes as well as in the volumes of the TT scintillator strips. The lead represents 93% of the target mass, the rest being emulsion films. Neutrino interactions occur not only in the target but also in other OPERA detector structures, such as spectrometers, in any material present in the experimental hall, including the BOREXINO [<cite linkend="nj384249bib11">11</cite>] detector and its related facilities, and in the surrounding rock. The ratio between the number of recorded interactions occurring inside and outside the target is about 1–6. As a consequence, primary vertexes have been generated in all of the above-mentioned volumes, since final state particles from any of these volumes may easily reach the OPERA target. Owing to the asymmetric beam energy profile, with a tail at very high energy, a large enough volume of rock has to be considered. Upstream of the detector, a cylinder of rock, 35 m in radius and 300 m in length, has been used in the simulation. The rock volume surrounding the detector has the shape of a cylinder with a radius of 35 m and an inner empty volume corresponding to the LNGS Hall C shape hosting the OPERA detector. MC studies show that 99% of the external events with hits reaching the OPERA detector are contained in a volume that is 35% smaller than the simulated one. Once primary vertexes are generated, the produced outgoing particles are propagated through the different simulated volumes and their interaction with matter, either with passive elements, such as the rock, or with a sensitive detector volume, is simulated using the GEANT3 [<cite linkend="nj384249bib12">12</cite>] Virtual MC simulation package, version 1.10.</p></sec-level2></sec-level1><sec-level1 id="nj384249s4" label="4"><heading>Event reconstruction</heading><p indent="no">In order to provide a comparison with the data, a reconstruction of the simulated neutrino interactions is performed, using the same algorithms as for real data, and the efficiencies of the different analysis steps, such as the selection of neutrino interactions with the primary vertex contained in the target, NC versus CC event tagging or muon identification, are evaluated.</p><sec-level2 id="nj384249s4.1" label="4.1"><heading>Selection of neutrino interaction events inside the target</heading><p indent="no">The OPERA DAQ system [<cite linkend="nj384249bib4">4</cite>, <cite linkend="nj384249bib13">13</cite>] records with high efficiency all of the interactions leaving a significant activity in the OPERA detector. To achieve this, the ED data are actually acquired in triggerless mode since the readout of the front-end electronics is asynchronous with the data, time stamped with a 10 ns clock. A minimum bias filter is applied at the level of subdetectors in order to reduce the detector noise. The event building is then performed by collecting all of the hits in a sliding time window of 3000 ns and requiring hits in the <inline-eqn><math-text><italic>x</italic></math-text></inline-eqn> and <inline-eqn><math-text><italic>y</italic></math-text></inline-eqn> projections of at least two TT planes or a TT plane with the sum of the photomultiplier signals exceeding 1500 ADC counts, and the presence of at least 10 hits.

Therefore an almost pure sample of 31 576 interactions in time with the beam, with the primary vertex contained inside or outside the OPERA target, was obtained for the 2008–2009 neutrino runs. As events occurring in the target represent a small fraction of the total number of recorded events, an automatic algorithm, OpCarac [<cite linkend="nj384249bib15">15</cite>], identifies such events, hereafter called ‘contained’ events. The contained events are more precisely those located in the target volume actually filled with bricks; this volume is fully instrumented by the TT, the walls of which are larger than the target walls. Events not fulfilling this requirement are hereafter called ‘external’ events. The OpCarac algorithm efficiency, estimated as the ratio between the number of MC events generated in the target volume and selected as contained to the total number of MC events generated, is high, as shown in table <tabref linkend="nj384249tab1">1</tabref>, in particular for CC events.</p><table id="nj384249tab1" frame="topbot" position="float" width="fit" place="top"><caption type="table" id="nj384249tc1" label="Table 1"><p>Efficiencies for the selection of contained events.</p></caption><tgroup cols="2"><colspec colnum="1" colname="col1" align="left"></colspec><colspec colnum="2" colname="col2" align="center"></colspec><thead><row><entry>Type</entry><entry>Contained fraction (%)</entry></row></thead><tbody><row><entry>CC</entry><entry><inline-eqn><math-text>97.6±1.4</math-text></inline-eqn></entry></row><row><entry>NC</entry><entry><inline-eqn><math-text>83.0±1.6</math-text></inline-eqn></entry></row></tbody></tgroup></table><p>The external events are mostly due to CC interactions occurring in the rock surrounding the detector. The final state muon is crossing the full detector or entering from the sides. These events are easily identified and rejected by OpCarac. The presence of the VETO system is particularly helpful when the muon is entering the detector from the front. The number of recorded external events with this topology was compared to MC expectations. The data and MC are in agreement within the 10% error on the expected number of <inline-eqn><math-text>ν<sub>μ</sub></math-text></inline-eqn> CC events due to the uncertainty on the total beam flux and on the <inline-eqn><math-text>ν<sub>μ</sub></math-text></inline-eqn> CC cross section. Further MC studies show that CC events occurring in the rock surrounding the Hall C volume, in which the final state muon escapes detection, can also generate secondary particles produced at a large angle with respect to the incoming neutrino direction and hence reaching the target volume. In this case, the observed activity is mainly concentrated at the edges of the TT. These events appear as low activity NC events. Dedicated MC studies show that the spatial distribution of the low activity NC events measured in data and MC agree within the quoted 10% uncertainty. Due to the low activity in the EDs, these events are difficult to distinguish from genuine NC events occurring in the target. The contribution of NC interactions outside the target volume to the external event sample was checked through MC to be 20% of the overall external sample. In order to keep the efficiency for NC events occurring in the target high, a contamination of external events is unavoidable. While the CC sample is basically free of external events, the contamination of the NC sample is at the 10% level and 3% for the whole NC+CC sample.</p></sec-level2><sec-level2 id="nj384249s4.2" label="4.2"><heading>Muon identification</heading><p indent="no">The muon identification performed by the EDs is of primary importance in the OPERA analysis flow because:</p><itemized-list id="list1" type="bullet" style="hanging"><list-item id="list1-i1"><p>The <inline-eqn><math-text>τ</math-text></inline-eqn> muonic decay is a ‘golden channel’ to tag the <inline-eqn><math-text>ν<sub>μ</sub></math-text></inline-eqn> to <inline-eqn><math-text>ν<sub>τ</sub></math-text></inline-eqn> oscillation since it is the only channel where the momentum and charge of the decay daughter can be measured.</p></list-item><list-item id="list1-i2"><p>The identification of a muon track originating from the primary vertex is of crucial importance to discard all of the <inline-eqn><math-text>ν<sub>μ</sub></math-text></inline-eqn> CC inclusive interactions, which are a source of background for the <inline-eqn><math-text>τ</math-text></inline-eqn> search.</p></list-item><list-item id="list1-i3"><p>The muon charge measurement allows one to discriminate muons coming from <inline-eqn><math-text>τ</math-text></inline-eqn> decay, with negative charge, from those produced by the decays of charmed particles, with positive charge.

It can be applied to all of the events; it is used for an evaluation of the NC/CC ratio, and it also provides a general veto for NC events. The second algorithm relies on the muon track reconstruction and it can therefore be applied only to events where a track exists; it is mandatory for the connection of the muon track between EDs and emulsions.</p><p>In the first algorithm, the criterion to classify CC and NC events is based on the total number of ED planes containing hits (<inline-eqn><math-text><italic>N</italic><sub><upright>ED</upright></sub></math-text></inline-eqn>). For the TT subdetector, <inline-eqn><math-text><italic>N</italic><sub><upright>ED</upright></sub></math-text></inline-eqn> is obtained by counting the number of walls with signals in either of the two orthogonal planes; for the RPC subdetector the number of planes with signals in either of the two orthogonal sets of readout strips is considered. The TT walls and the RPC planes are equally treated in this calculation. The energy lost by a minimum ionizing particle between two consecutive RPC planes is 57.1 MeV. Between two TT walls it is 71.4 MeV, 25% larger. The corresponding numbers of interaction lengths are, respectively, 0.298 and 0.328, 10% larger. The ratio between <inline-eqn><math-text><upright>d</upright><italic>E</italic>/<upright>d</upright><italic>x</italic></math-text></inline-eqn> and the interaction length of the two media is not so large as to justify a different treatment in the algorithm applied.

The track reconstruction relies on a sequence of algorithms. Primarily the ED hits are connected to form tracks in both longitudinal projections by a pattern recognition algorithm. Then the three-dimensional (3D) tracks are reconstructed by associating tracks in the two projections. A Kalman filter [<cite linkend="nj384249bib17">17</cite>] is also used to calculate the momentum and to reject hits wrongly assigned to tracks. The length times density is then computed and used to identify a generic track as a muon track. The length is defined by adding straight distances between consecutive TT and/or RPC hits (TT walls are spaced apart by about 13 cm and RPC planes by about 7 cm) along the whole track length. The actual detector structure along the track path fixes the value to be used for density. The muon identification criterion is based on a cut on the length times density of the longest reconstructed 3D track in the event. Requiring a muon identification at the level of 95% implies a cut at <inline-eqn><math-text>660 <upright>g</upright> <upright>cm</upright><sup>−2</sup></math-text></inline-eqn>. The length times density distributions for data and MC, above the selection cut, are shown in figure <figref linkend="nj384249fig5">5</figref>, where the MC distribution has been normalized to the data. The MC simulation reproduces the data trend well. For each track identified as a muon by the length times density criterion, the algorithm provides an estimate of the momentum. If the track stops in the target or leaves the target but does not fully cross at least one spectrometer arm, the energy is measured by range and the charge measurement is not available. MC studies show that the NC contamination of the sample of events with at least one muon track is 5.2%. In the sample of events where a spectrometer is crossed, the NC contamination is as small as 0.8%. In addition, if at least one muon with negative charge is required, the contamination drops to 0.4%.</p><figure id="nj384249fig5" parts="single" width="column" position="float" pageposition="top" printstyle="normal" orientation="port"><graphic position="indented"><graphic-file version="print" format="EPS" width="26.0pc" printcolour="no" filename="images/nj384249fig5.eps"></graphic-file><graphic-file version="ej" format="JPEG" printcolour="no" filename="images/nj384249fig5.jpg"></graphic-file></graphic><caption type="figure" id="nj384249fc5" label="Figure 5"><p indent="no">Length <inline-eqn><math-text>×</math-text></inline-eqn> density comparison for data (dots with error bars) and MC (solid line) for events classified as CC (i.e. length <inline-eqn><math-text>×</math-text></inline-eqn> density <inline-eqn><math-text>>660 <upright>g</upright> <upright>cm</upright><sup>−2</sup></math-text></inline-eqn>).

Varying the cut from 10 to 25 planes, the maximum discrepancy between data and MC in the NC-to-CC ratio is <inline-eqn><math-text>±0.019</math-text></inline-eqn>. Another source of systematics comes from the uncertainties in the contained events selection algorithm. As can be seen in table <tabref linkend="nj384249tab1">1</tabref>, 17% of the NC MC events are not selected. Out of these, 4.2% are discarded since they would not fulfil the trigger condition (see section <secref linkend="nj384249s4.1">4.1</secref>). The remaining 12.8% of the events are in a transition region, with little activity recorded in the detector. Conservatively, a 50% error is assumed for this particular topology of NC events. The same computation for the CC events gives about a 1% error. This propagates into an error of <inline-eqn><math-text>±0.015</math-text></inline-eqn> on the final result. In order to check for additional systematic uncertainties due to the contained event selection algorithm, data and MC calculations for the NC-to-CC ratio are repeated using events with the primary vertex in the first and the second SM separately. No difference is found in either the simulation or the real data where the values obtained for the ratio agree within 1 sigma. Therefore, a possible contribution to the systematic error of the measurement is negligible.</p><p>The last source of uncertainties is on the number of external events that affect mostly the NC sample. This uncertainty is obtained by inspecting the agreement between data and MC in variables that are particularly sensitive to the external background component, such as the visible energy and the 3D position of the events. While genuine NC events are uniformly distributed inside the target, external events tend to be more concentrated towards the edges. This analysis showed that the expected number of background events in data and MC are in reasonable agreement, within an uncertainty safely estimated to be in the range of <inline-eqn><math-text>−15</math-text></inline-eqn> to <inline-eqn><math-text>+24</math-text></inline-eqn>%.

For this test, it is desirable to use a sample with a reduced NC contamination in order to disentangle the true muon reconstruction from possible effects due to background hadron tracks. Therefore, all events are required to have their muon momentum measured from the bending in the spectrometer. In addition, a negative measured charge is required. The measured muon momentum distribution is shown in figure <figref linkend="nj384249fig6">6</figref> and compared to MC expectations. The MC has been normalized to the number of p.o.t. corresponding to the 2008–2009 data sample. The error in the MC prediction is obtained after taking into account the uncertainty in the value of the magnetic field, which translates into a 3% shift of the MC spectrum, and the already quoted 10% uncertainty on the expected number of <inline-eqn><math-text>ν<sub>μ</sub></math-text></inline-eqn> CC events, the latter being the dominant source of uncertainty.

A signal is measured at each end of the scintillator strips in terms of ADC counts (see [<cite linkend="nj384249bib18">18</cite>] for details), and then converted into a number of photo-electrons (p.e.) according to the gain of the photomultiplier (PMT) channel. The sum of the number of p.e. measured on both sides is converted into an energy deposit (in MeV), according to the position of the hit along the strip and to a calibration curve that accounts for the attenuation of the signal along the strip fibre. This calibration has been performed using radioactive sources before detector assembly and cosmic ray data. First, the dependence of the number of p.e. of a minimum ionizing particle (mip) on the crossing position along the strip has been validated (see section <secref linkend="nj384249s5.3.1">5.3.1</secref>) and used to compute the visible energy.

Nine planes in each SM are also used to generate a fast trigger signal used as an external trigger by the drift tubes of the PTs. This trigger signal is also accurately computed in the simulation. Due to the different widths of the horizontal and vertical sets of readout strips, a slightly different efficiency is implemented in the MC simulation. The efficiency in the MC is tuned from the observed multiplicity of vertical and horizontal strips measured for neutrino-induced muon tracks. From these data and from cosmic ray data, the average strip efficiency measured <italic>in situ</italic> exceeds 95%. The stability of the performances is monitored using cosmic ray data.</p></sec-level2><sec-level2 id="nj384249s7.2" label="A.2"><heading>Simulation of the precision trackers (PTs)</heading><p indent="no">If a charged particle passes through the gas-filled volume of a PT drift tube, the hits in this volume are recorded, as well as the corresponding time. The hit closest to the sense wire is taken to determine the drift time using a drift time to distance relation. In addition, the drift time is smeared using a resolution function. The time information of the RPC hits in planes contributing to the trigger is used to generate a trigger time. The signal propagation delays in all corresponding cables and in the RPC strips are taken into account for a realistic simulation of the trigger time delay. The resulting trigger time is then subtracted from the time of the drift tube hit and this difference is used as an offset for the drift time. Thus trigger effects and the time of flight between the trigger planes and the drift tubes are properly accounted for. Also, the signal propagation delay on the drift tube wires and the signal cables is taken into account. In the simulation, the single tube efficiency is set to 99%. If no trigger is generated in an SM, no drift tube data are saved for this SM. The time to distance relation, the resolution function and the single tube efficiency have been determined using a test setup outside the LNGS, with the same operational parameters as those used onsite. Detector alignment is performed during dedicated cosmic ray runs without magnetic field. <italic>In situ</italic>, performances are monitored using cosmic ray data.</p></sec-level2><sec-level2 id="nj384249s7.3" label="A.3"><heading>Simulation of the target tracker (TT)</heading><p indent="no">When a particle is tracked through the volume occupied by a TT scintillator strip, the energy deposited and the time are recorded. A corresponding light signal is generated, and the attenuation and the delay in the propagation through the strip via the WLS fibre up to the corresponding photomultiplier channel are computed. The signal is converted into a number of p.e. With the chosen threshold (1/3 of p.e.), the mean detection efficiency for a minimum ionizing particle crossing the strip in the middle is higher than 99%. To make the detector description as realistic as possible, the crosstalk has also been included, i.e. the possibility that the signal deposited in one TT strip is recorded on a neighbouring photomultiplier channel. Calibrations are periodically performed and efficiencies, obtained from neutrino interaction data or cosmic ray data, are compared with the MC simulation. Using MC data, it is then possible to correlate the visible energy in the TT with the incoming neutrino energy. In the presence of an energy leakage from the TT into the spectrometer, the RPC data are also explicitly taken into account by the algorithm. The energy resolution reached is shown in figure <figref linkend="nj384249figA1">A.1</figref>.</p><figure id="nj384249figA1" parts="single" width="column" position="float" pageposition="top" printstyle="normal" orientation="port"><graphic position="indented"><graphic-file version="print" format="EPS" width="21.9pc" printcolour="no" filename="images/nj384249figA1.eps"></graphic-file><graphic-file version="ej" format="JPEG" printcolour="yes" filename="images/nj384249figA.1.jpg"></graphic-file></graphic><caption type="figure" id="nj384249fcA1" label="Figure A.1"><p indent="no">MC energy resolution computed using the CNGS neutrino energy spectrum.</p></caption></figure></sec-level2></sec-level1></appendix></body><back><references><heading>References</heading><reference-list type="numeric"><misc-ref id="nj384249bib1" num="1"><authors><au><second-name>Guler</second-name><first-names>M</first-names></au><others><italic>et al</italic></others><collaboration>(<group>OPERA Collaboration</group>)</collaboration></authors><year>2000</year><misc-text>CERN-SPSC-2000-028</misc-text></misc-ref><misc-ref id="nj384249bib2" num="2"><authors><au><second-name>Elsener</second-name><first-names>E K</first-names></au></authors><year>1998</year><misc-text>CERN 98-02, INFN/AE-98/05, CNGS project, <webref url="http://proj-cngs.web.cern.ch/proj-cngs/">http://proj-cngs.web.cern.ch/proj-cngs/</webref></misc-text></misc-ref><journal-ref id="nj384249bib3" num="3"><authors><au><second-name>Agafonova</second-name><first-names>N</first-names></au><others><italic>et al</italic></others><collaboration>(<group>OPERA Collaboration</group>)</collaboration></authors><year>2010</year><jnl-title>Phys.

OPERA experiment is based on a hybrid technology combining electronic detectors (EDs) and nuclear emulsions. OPERA collected muonneutrino interactions during the 2008 and 2009 physics runs of the CNGS neutrino beam, produced at CERN with an energy range of about 535GeV. A total of 5.31019 protons on target equivalent luminosity have been analysed with the OPERA EDs: scintillator strips target trackers and magnetic muon spectrometers equipped with resistive plate gas chambers and drift tubes, allowing a detailed reconstruction of muonneutrino interactions. Charged current (CC) and neutral current (NC) interactions are identified, using the measurements in the EDs, and the NC/CC ratio is computed. The momentum distribution and the charge of the muon tracks produced in CC interactions are analysed. Calorimetric measurements of the visible energy are performed for both the CC and NC samples. For CC events, the Bjorken-y distribution and the hadronic shower profile are computed. The results are compared with a detailed Monte Carlo simulation of the response of EDs.</abstract><relatedItem type="host"><titleInfo><title>New Journal of Physics</title></titleInfo><titleInfo type="abbreviated"><title>New J.
