11.3. High Energy Neutrinos
Waxman & Bahcall  suggested that collisions between protons and photons within the relativistic fireball shocks produce pions. These pions produce high energy neutrinos with E ~ 1014 eV and fhigh energy - > 0.1. The flux of these neutrinos is comparable to the flux of atmospheric neutrinos but those will be correlated with the position of strong GRBs. This signal might be detected in future km2 size neutrino detectors.
