Contribution

It introduces a detailed analysis of neutrino production in both fireball and MHD models of GRB outflows, highlighting differences in neutrino signals.

Findings

Neutrino production is significant in inelastic neutron-proton collisions.

Differences in neutrino fluxes between fireball and MHD models are identified.

Potential for neutrino detection to distinguish GRB models.

Abstract

Neutrinos produced in gamma-ray bursters (GRBers) may provide a unique probe for the physics of these extreme astrophysical systems. Here we discuss neutrino production in inelastic neutron-proton collisions within the relativistic outflows associated with GRBers. We consider both the widely used fireball model and a recently proposed magneto-hydrodynamic (MHD) model for the GRB outflow.
