Abstract

We investigate the expected neutrino emissivity from nuclear collisions in a magnetically dominated model of gamma-ray bursts motivated by recent observational and theoretical developments. The results indicate that small multi-GeV neutrino fluxes are expected for model parameter values which are typical of electromagnetically detected bursts. We show that for detecting at least one muon event in IceCube and its DeepCore subarray, a single burst must be near the high end of the luminosity function, and at low redshifts z0.1, where the burst rate is very low. We also calculate the luminosity and distance ranges which can generate 0.01–1 muon events per gamma-ray burst in the same detectors, which may be of interest if simultaneously detected electromagnetically, or if measured with future extensions of IceCube or other neutrino detectors with larger effective volume and better sensitivity.
