Sensitivity of JEM-EUSO to GRB Neutrinos
Abstract
JEM-EUSO is a mission to study ultra-high-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 \v{C}erenkov light from the earth skimming tau neutrinos at the energy range of eV. In this paper we will discuss high-energy tau neutrinos from nearby gamma-ray bursts (GRBs). From simulations of cascade in GRB photon fields including various hadronic/leptonic processes, we estimate the neutrino flux from GRBs. Our results show that both muons and pions are dominant sources of neutrinos at the energy range of eV. We discuss the possibility of detecting the \v{C}erenkov light of upward going showers from Earth skimming tau neutrinos coming from some closest GRBs.
