High Energy Neutrinos from Cosmological Gamma-Ray Burst Fireballs

Observations suggest that {gamma}-ray bursts (GRBs) are produced by the dissipation of the kinetic energy of a relativistic fireball. We show that a large fraction, {ge}10{percent}, of the fireball energy is expected to be converted by photomeson production to a burst of {approximately}10{sup 14}eV...

Zusammenfassung:Observations suggest that {gamma}-ray bursts (GRBs) are produced by the dissipation of the kinetic energy of a relativistic fireball. We show that a large fraction, {ge}10{percent}, of the fireball energy is expected to be converted by photomeson production to a burst of {approximately}10{sup 14}eV neutrinos. A km{sup 2} neutrino detector would observe at least several tens of events per year correlated with GRBs, and test for neutrino properties (e.g., flavor oscillations, for which upward moving {tau}{close_quote}s would be a unique signature, and coupling to gravity) with an accuracy many orders of magnitude better than is currently possible. {copyright} {ital 1997} {ital The American Physical Society}
