11.3. High Energy Neutrinos

Waxman & Bahcall [297] 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 f_{high 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.
