Description
The physical mechanism at the origin of gamma-ray bursts (GRBs) is far from being completely understood. Describing their emission up to very high energies (GeV-TeV) is one of the most challenging and important tasks needed to unveil the physics of these peculiar events.
Using data collected by the HAWC gamma-ray observatory, we search for TeV emission coming from a sample of GRBs detected by Fermi and Swift between December 2014 and May 2017. We derive upper limits derived over different time intervals and use them to constrain the microphysical parameters and the bulk Lorentz factor under the assumption of the external shock model scenario. We present the results of this analysis discussing possible interpretations.
