Title: "Ultra-High-Energy Cosmic Rays and neutrinos from Gamma-Ray Bursts?"
Abstract: I discuss the multi-messenger emission from GRBs, assuming that these are the sources of the UHECRs. I demonstrate how the non-observation of astrophysical neutrinos from GRBs constrains the UHECR paradigm, how the multi-messenger connection depends on the outflow model, what radiative signatures of UHECRs can be expected in the electromagnetic spectrum, and what we can learn from energetic GRBs, such as GRB 221009A.
