Abstract:
'Neutrino emission from Gamma-Ray Bursts (GRBs) has been heavily investigated in the last decades  providing a wealth of models which, under different physical conditions, are able to reproduce the observed electromagnetic gamma-ray emission. Among these, the most exploited ones provide gamma rays, produced in the optically thin region of the jet from neutral pion decay, as well as neutrinos emitted in the TeV-PeV energy range as a result of charged pion decay. To date, though, no successful detection of such high-energy neutrinos from GRBs has been realized. However, within the framework of the so-called ‘inelastic collision model’, also lower energy neutrinos (GeV and sub-TeV ranges) could be produced from a dissipation mechanism through hadronic collisions (pp or pn) around or below the photosphere, where the jet is still optically thick. So far, dedicated searches for such low-energy neutrinos have not been undertaken yet. In the present work, we report preliminary detection prospects for neutrinos produced in collisionally heated GRBs, with KM3NeT and IceCube, as well as considering their low-energy extensions (ORCA and DeepCore, respectively).'
