Earth–skimming UHE Tau Neutrinos at the Fluorescence Detector of Pierre Auger Observatory
Ultra high energy neutrinos are produced by the interaction of hadronic cosmic rays with the cosmic radiation background. More exotic scenarios like topological defects or new hadrons predict even larger fluxes. In particular, Earth–skimming tau neutrinos could be detected by the Fluorescence Detector (FD) of Pierre Auger Observatory. A detailed evaluation of the expected number of events has b...
متن کاملEnhanced signal of astrophysical tau neutrinos propagating through Earth
Earth absorbs ne and nm of energies above about 100 TeV. As is well known, although nt will also disappear through charged-current interactions, the nt flux will be regenerated by prompt tau decays. We show that this process also produces relatively large fluxes of secondary n̄e and n̄m , greatly enhancing the detectability of the initial nt . This is particularly important because at these energ...
متن کاملThe Relevance of Mediterranean Neutrino Telescope Sites on Earth-skimming tau neutrino detection
Neutrinos are one of the main components of the cosmic radiation in the ultra-high energy (UHE) regime. Although their fluxes are uncertain and depend on the production mechanism, their detection can provide information on the sources and origin of the UHE cosmic rays. For example, UHE neutrinos can be produced via πphotoproduction by strongly accelerated hadrons in presence of a background ele...
متن کاملThe sensitivity of the surface detector of the Pierre Auger Observatory to UHE Earth-skimming and down-going neutrinos
The Pierre Auger Observatory is sensitive to ultra-high energy neutrinos in the EeV range and above. In this work we describe the complete chain needed to compute the neutrino acceptance of the surface detector. We firstly address the computation of the probability that an ultra-high energy neutrino produces an air shower. Subsequently we present the simulations to deduce the detector response ...
متن کاملSensitivity of JEM-EUSO to GRB Neutrinos
JEM-EUSO is a mission to study ultrahigh-energy cosmic rays (UHECRs) by measuring the fluorescence light from giant air showers at the altitude of the International Space Station. In the tilted mode, JEM-EUSO will become very sensitive to the Čerenkov light from the earth skimming tau neutrinos at the energy range of 10eV. In this paper we will discuss high-energy tau neutrinos from nearby gamm...
