Abstract
Abstract: With additional data and improved algorithms, we have enhanced the sensitivity of our appearance search for νμ→ντ oscillations in the NOMAD detector in the CERN-SPS wide-band neutrino beam. The search uses kinematic criteria to identify ντ charged current interactions followed by decay of the τ− to one of several decay modes. Our “blind” analyses of deep-inelastic scattering data taken in 1996 and 1997, combined with consistent reanalyses of previously reported 1995 data, yield no oscillation signal. For the two-family oscillation scenario, we present the contour outlining a 90% C.L. confidence region in the sin22θμτ–Δm2 plane. At large Δm2, the confidence region includes sin22θμτ<1.2×10−3 (a limit 3.5 times more stringent than in our previous publication), while at sin22θμτ=1, the confidence region includes Δm2<1.2 eV2/c4.

xml:lang="en">Abstract: With additional data and improved algorithms, we have enhanced the sensitivity of our appearance search for νμ→ντ oscillations in the NOMAD detector in the CERN-SPS wide-band neutrino beam. The search uses kinematic criteria to identify ντ charged current interactions followed by decay of the τ− to one of several decay modes. Our “blind” analyses of deep-inelastic scattering data taken in 1996 and 1997, combined with consistent reanalyses of previously reported 1995 data, yield no oscillation signal. For the two-family oscillation scenario, we present the contour outlining a 90% C.L. confidence region in the sin22θμτ–Δm2 plane. At large Δm2, the confidence region includes sin22θμτ<1.2×10−3 (a limit 3.5 times more stringent than in our previous publication), while at sin22θμτ=1, the confidence region includes Δm2<1.2 eV2/c4.</div></front></TEI><istex><corpusName>elsevier</corpusName><keywords><teeft><json:string>physics

The search uses kinematic criteria to identify ντ charged current interactions followed by decay of the τ− to one of several decay modes. Our “blind” analyses of deep-inelastic scattering data taken in 1996 and 1997, combined with consistent reanalyses of previously reported 1995 data, yield no oscillation signal. For the two-family oscillation scenario, we present the contour outlining a 90% C.L. confidence region in the sin22θμτ–Δm2 plane. At large Δm2, the confidence region includes sin22θμτ>1.2×10−3 (a limit 3.5 times more stringent than in our previous publication), while at sin22θμτ=1, the confidence region includes Δm2>1.2 eV2/c4.</abstract><qualityIndicators><score>8.488</score><pdfWordCount>8315</pdfWordCount><pdfCharCount>42462</pdfCharCount><pdfVersion>1.2</pdfVersion><pdfPageCount>18</pdfPageCount><pdfPageSize>540 x 712 pts</pdfPageSize><refBibsNative>true</refBibsNative><abstractWordCount>124</abstractWordCount><abstractCharCount>845</abstractCharCount><keywordCount>1</keywordCount></qualityIndicators><title>A more sensitive search for ν μ → ν τ oscillations in NOMAD</title><pii><json:string>S0370-2693(99)00303-2</json:string></pii><corporate><json:item><name>NOMAD Collaboration</name></json:item></corporate><genre><json:string>research-article</json:string></genre><host><title>Physics Letters B</title><language><json:string>unknown</json:string></language><publicationDate>1999</publicationDate><issn><json:string>0370-2693</json:string></issn><pii><json:string>S0370-2693(00)X0220-1</json:string></pii><volume>453</volume><issue>1–2</issue><pages><first>169</first><last>186</last></pages><genre><json:string>journal</json:string></genre></host><namedEntities><unitex><date><json:string>1997</json:string><json:string>1999</json:string><json:string>1995, 1996, and 1997</json:string><json:string>1995</json:string><json:string>1500</json:string><json:string>1996</json:string></date><geogName></geogName><orgName><json:string>Department of Energy, National Science Foundation Žgrant PHY</json:string><json:string>and Department of Industry, Science, and Resources ŽDISR</json:string><json:string>Institute, Zagreb, Croatia</json:string><json:string>Research, INR Moscow, Russia</json:string><json:string>Russian Foundation for Basic Research, Institute for Nuclear Research of the Russian Academy of Sciences, Russia</json:string><json:string>European Commission</json:string><json:string>France Johns Hopkins</json:string><json:string>Fonds National Suisse</json:string><json:string>Istituto Nazionale</json:string><json:string>Australian Research Council ŽARC</json:string></orgName><orgName_funder></orgName_funder><orgName_provider></orgName_provider><persName><json:string>P.

The search uses kinematic criteria to identify ντ charged current interactions followed by decay of the τ− to one of several decay modes. Our “blind” analyses of deep-inelastic scattering data taken in 1996 and 1997, combined with consistent reanalyses of previously reported 1995 data, yield no oscillation signal. For the two-family oscillation scenario, we present the contour outlining a 90% C.L. confidence region in the sin22θμτ–Δm2 plane. At large Δm2, the confidence region includes sin22θμτ<1.2×10−3 (a limit 3.5 times more stringent than in our previous publication), while at sin22θμτ=1, the confidence region includes Δm2<1.2 eV2/c4.</p></abstract><textClass><keywords scheme="keyword"><list><head>Keywords</head><item><term>Neutrino oscillations</term></item></list></keywords></textClass></profileDesc><revisionDesc><change

The search uses kinematic criteria to identify ντ charged current interactions followed by decay of the τ− to one of several decay modes. Our “blind” analyses of deep-inelastic scattering data taken in 1996 and 1997, combined with consistent reanalyses of previously reported 1995 data, yield no oscillation signal. For the two-family oscillation scenario, we present the contour outlining a 90% C.L. confidence region in the sin22θμτ–Δm2 plane. At large Δm2, the confidence region includes sin22θμτ<1.2×10−3 (a limit 3.5 times more stringent than in our previous publication), while at sin22θμτ=1, the confidence region includes Δm2<1.2 eV2/c4.</abstract><note>Editor: L.

The large box at the upper right corner indicates the signal region and is divided into sub-boxes.</note><note type="content">Fig. 3: Histogram of lnλe2 for events passing all cuts except the one on lnλe2, for sum of simulated backgrounds (shaded), τ−→e− ν ̄eντ simulation (unshaded), and data (points with statistical error bars). The inset gives, for each value of lnλe2, the total number of events beyond that value, for data (dots) and expected background (squares); the encircled points are at the boundary of the signal region.</note><note type="content">Fig. 4: Distributions from the search for τ−→h−(nπ0)ντ: (a) lnλhμ for νμ CC background and for signal; (b) lnλhkin; (c) QT, after transformation to the metric in which the signal density is uniform from 0 to 1; (d) ρm, after transformation to the metric in which the signal density is uniform from 0 to 1; (e) the integrated number of h− events above a given lnλhkin value for the predicted background and for the data; and (f) the corresponding plot for the τ+ control search.
