Abstract
Abstract: We report on a search for heavy neutrinos (ν4) produced in the decay Ds→τν4 at the SPS proton target followed by the decay ν4→ντe+e− in the NOMAD detector. Both decays are expected to occur if ν4 is a component of ντ. From the analysis of the data collected during the 1996–1998 runs with 4.1×1019 protons on target, a single candidate event consistent with background expectations was found. This allows to derive an upper limit on the mixing strength between the heavy neutrino and the tau neutrino in the ν4 mass range from 10 to 190 MeV. Windows between the SN1987a and Big Bang Nucleosynthesis lower limits and our result are still open for future experimental searches. The results obtained are used to constrain an interpretation of the time anomaly observed in the KARMEN1 detector.

Both decays are expected to occur if ν4 is a component of ντ. From the analysis of the data collected during the 1996–1998 runs with 4.1×1019 protons on target, a single candidate event consistent with background expectations was found. This allows to derive an upper limit on the mixing strength between the heavy neutrino and the tau neutrino in the ν4 mass range from 10 to 190 MeV. Windows between the SN1987a and Big Bang Nucleosynthesis lower limits and our result are still open for future experimental searches. The results obtained are used to constrain an interpretation of the time anomaly observed in the KARMEN1 detector.</div></front></TEI><istex><corpusName>elsevier</corpusName><keywords><teeft><json:string>neutrino</json:string><json:string>phys</json:string><json:string>nomad</json:string><json:string>lett</json:string><json:string>nucl</json:string><json:string>photon</json:string><json:string>nomad collaboration physics letters</json:string><json:string>instrum</json:string><json:string>infn</json:string><json:string>nomad detector</json:string><json:string>isosinglet</json:string><json:string>heavy neutrinos</json:string><json:string>upper limit</json:string><json:string>nomad collaboration</json:string><json:string>signal region</json:string><json:string>neutrino interactions</json:string><json:string>selection criteria</json:string><json:string>heavy neutrino</json:string><json:string>isosinglet neutrino</json:string><json:string>proton target</json:string><json:string>anomaly</json:string><json:string>primary vertex</json:string><json:string>background estimate</json:string><json:string>drift chambers</json:string><json:string>ducial volume</json:string><json:string>bremsstrahlung photons</json:string><json:string>time anomaly</json:string><json:string>decay channel</json:string><json:string>mass range</json:string><json:string>bang nucleosynthesis</json:string><json:string>correction factor</json:string><json:string>simulation</json:string><json:string>detector</json:string><json:string>energy region</json:string><json:string>decay rate</json:string><json:string>decay mode</json:string><json:string>invariant mass</json:string><json:string>scintillation counters</json:string><json:string>signal events</json:string><json:string>neutrino target</json:string><json:string>data sample</json:string><json:string>decay tunnel</json:string><json:string>pair reconstruction</json:string><json:string>double ratio</json:string><json:string>next step</json:string><json:string>opening angle</json:string><json:string>higher energies</json:string><json:string>secondary hadrons</json:string><json:string>neutrino experiments</json:string><json:string>second method</json:string><json:string>karmen collaboration</json:string><json:string>neutrino beam</json:string><json:string>mass region</json:string><json:string>mass differences</json:string><json:string>charm collaboration</json:string><json:string>nutev collaboration</json:string><json:string>massive neutrinos</json:string><json:string>energy spectra</json:string></teeft></keywords><author><json:item><name>P.

Both decays are expected to occur if ν4 is a component of ντ. From the analysis of the data collected during the 1996–1998 runs with 4.1×1019 protons on target, a single candidate event consistent with background expectations was found. This allows to derive an upper limit on the mixing strength between the heavy neutrino and the tau neutrino in the ν4 mass range from 10 to 190 MeV. Windows between the SN1987a and Big Bang Nucleosynthesis lower limits and our result are still open for future experimental searches. The results obtained are used to constrain an interpretation of the time anomaly observed in the KARMEN1 detector.</abstract><qualityIndicators><refBibsNative>true</refBibsNative><abstractWordCount>134</abstractWordCount><abstractCharCount>800</abstractCharCount><keywordCount>3</keywordCount><score>8.608</score><pdfWordCount>5870</pdfWordCount><pdfCharCount>29108</pdfCharCount><pdfVersion>1.2</pdfVersion><pdfPageCount>12</pdfPageCount><pdfPageSize>543 x 744 pts</pdfPageSize></qualityIndicators><title>Search for heavy neutrinos mixing with tau neutrinos</title><pii><json:string>S0370-2693(01)00362-8</json:string></pii><corporate><json:item><name>NOMAD Collaboration</name></json:item></corporate><genre><json:string>brief-communication</json:string></genre><host><title>Physics Letters B</title><language><json:string>unknown</json:string></language><publicationDate>2001</publicationDate><issn><json:string>0370-2693</json:string></issn><pii><json:string>S0370-2693(00)X0331-0</json:string></pii><volume>506</volume><issue>1–2</issue><pages><first>27</first><last>38</last></pages><genre><json:string>journal</json:string></genre></host><namedEntities><unitex><date><json:string>2001</json:string><json:string>1996</json:string></date><geogName></geogName><orgName><json:string>University of Sydney</json:string><json:string>University of Padova</json:string><json:string>Institute, Zagreb, Croatia</json:string><json:string>Johns Hopkins University</json:string><json:string>Switzerland Received</json:string><json:string>University of Pisa</json:string><json:string>University of Florence</json:string><json:string>and Department of Industry, Science, and Resources</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>Australian Research Council</json:string><json:string>University of Urbino</json:string><json:string>ARC</json:string><json:string>University of Lausanne</json:string><json:string>Department of Energy, National Science Foundation</json:string><json:string>University of Paris</json:string><json:string>Harvard University</json:string><json:string>Institute Nuclear Research, INR Moscow, Russia</json:string><json:string>University of South Carolina</json:string><json:string>University of Pavia</json:string><json:string>Roma Tre University</json:string><json:string>University of Melbourne</json:string><json:string>DISR</json:string><json:string>Fonds National Suisse</json:string><json:string>Dortmund University</json:string><json:string>Istituto Nazionale</json:string><json:string>University of Calabria</json:string><json:string>University of Perugia</json:string></orgName><orgName_funder></orgName_funder><orgName_provider></orgName_provider><persName><json:string>P.

xml:lang="en"><p>We report on a search for heavy neutrinos (ν4) produced in the decay Ds→τν4 at the SPS proton target followed by the decay ν4→ντe+e− in the NOMAD detector. Both decays are expected to occur if ν4 is a component of ντ. From the analysis of the data collected during the 1996–1998 runs with 4.1×1019 protons on target, a single candidate event consistent with background expectations was found. This allows to derive an upper limit on the mixing strength between the heavy neutrino and the tau neutrino in the ν4 mass range from 10 to 190 MeV. Windows between the SN1987a and Big Bang Nucleosynthesis lower limits and our result are still open for future experimental searches. The results obtained are used to constrain an interpretation of the time anomaly observed in the KARMEN1 detector.</p></abstract><textClass><keywords

Both decays are expected to occur if <ce:italic>ν</ce:italic><ce:inf>4</ce:inf> is a component of <ce:italic>ν</ce:italic><ce:inf><ce:italic>τ</ce:italic></ce:inf>. From the analysis of the data collected during the 1996–1998 runs with 4.1×10<ce:sup>19</ce:sup> protons on target, a single candidate event consistent with background expectations was found. This allows to derive an upper limit on the mixing strength between the heavy neutrino and the tau neutrino in the <ce:italic>ν</ce:italic><ce:inf>4</ce:inf> mass range from 10 to 190 MeV. Windows between the SN1987a and Big Bang Nucleosynthesis lower limits and our result are still open for future experimental searches. The results obtained are used to constrain an interpretation of the time anomaly observed in the KARMEN1 detector.</ce:simple-para></ce:abstract-sec></ce:abstract><ce:keywords><ce:section-title>Keywords</ce:section-title><ce:keyword><ce:text>Neutrino

by the decay ν4→ντe+e− in the NOMAD detector. Both decays are expected to occur if ν4 is a component of ντ. From the analysis of the data collected during the 1996–1998 runs with 4.1×1019 protons on target, a single candidate event consistent with background expectations was found. This allows to derive an upper limit on the mixing strength between the heavy neutrino and the tau neutrino in the ν4 mass range from 10 to 190 MeV. Windows between the SN1987a and Big Bang Nucleosynthesis lower limits and our result are still open for future experimental searches. The results obtained are used to constrain an interpretation of the time anomaly observed in the KARMEN1 detector.</abstract><note>Editor: L.
