Systematic parameter space study for the UHECR origin from GRBs in models with multiple internal shocks

Systematic parameter space study for the UHECR origin from GRBs in models with multiple internal shocks

We scrutinize the paradigm that conventional long-duration Gamma-Ray Bursts (GRBs) are the dominant source of the ultra-high energy cosmic rays (UHECRs) within the internal shock scenario by describing UHECR spectrum and composition and by studying the predicted (source and cosmogenic) neutrino fluxes. Since it has been demonstrated that the stacking …
