J.2013-10-15T15:13:42Z2013-10-15T15:13:42Z20091550-7998http://www.repositorio.ufba.br/ri/handle/ri/13219v. 79, n. 10p. 1-15Data collected at the Pierre Auger Observatory are used to establish an upper limit on the diffuse flux of tau neutrinos in the cosmic radiation. Earth-skimming ντ may interact in the Earth’s crust and produce a τ lepton by means of charged-current interactions. The τ lepton may emerge from the Earth and decay in the atmosphere to produce a nearly horizontal shower with a typical signature, a persistent electromagnetic component even at very large atmospheric depths. The search procedure to select events induced by τ decays against the background of normal showers induced by cosmic rays is described. The method used to compute the exposure for a detector continuously growing with time is detailed. Systematic uncertainties in the exposure from the detector, the analysis, and the involved physics are discussed. No τ neutrino candidates have been found. For neutrinos in the energy range 2×1017  eV<Eν<2×1019  eV, assuming a diffuse spectrum of the form Eν-2, data collected between 1 January 2004 and 30 April 2008 yield a 90% confidence-level upper limit of Eν2dNντ/dEν<9×10-8  GeV  cm-2 s-1  sr-1.Submitted by Suelen Reis (suziy.ellen@gmail.com) on 2013-10-11T12:44:13Z No. of bitstreams: 1 PhysRevD.79.102001-1.pdf: 408996 bytes, checksum: ddbcc9313d304e92e781f683faa7672b (MD5)Approved for entry into archive by Rodrigo Meirelles(rodrigomei@ufba.br) on 2013-10-15T15:13:42Z (GMT) No. of bitstreams: 1 PhysRevD.79.102001-1.pdf: 408996 bytes, checksum: ddbcc9313d304e92e781f683faa7672b (MD5)Made available in DSpace on 2013-10-15T15:13:42Z (GMT).
