Description
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 in terms of multi-messenger signals involve neutrinos produced in the optically thin region of the jet, which are expected to be emitted in the TeV-PeV energy range. To date, 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 such neutrinos, produced in collisionally heated GRBs, with KM3NeT and IceCube, considering also their low-energy extensions (ORCA and DeepCore, respectively). In addition, we compare such predictions with the performances that the large volume neutrino telescopes are expected to achieve towards more classical models (e.g. internal shocks), which produce neutrinos with higher energies.
