Abstract

Gamma-ray bursts are observed to emit at least up to GeV energies, and their photon spectrum at the source is expected to extend up to TeV, due to either or both leptonic and hadronic mechanisms. I review some recent developments in GRB phenomenology in the light of Swift and other sub-MeV measurement, as well as recent theoretical work. I discuss then the acceleration of cosmic rays in GRB, which can extend to GZK energies, and the possibility of acceleration in GRB- related or other hypernovae. In both, synchrotron and inverse Compton, as well as hadronic processes, can lead to GeV-TeV gamma-rays measurable by GLAST, AGILE, or ACTs, providing useful probes of the burst physics and model parameters. Photo-meson and pp interactions also produce neutrinos at energies ranging from sub-TeV to EeV, which are targets for experiments such as IceCube, ANITA and KM3NeT.
