Constraints on Cosmic Rays Acceleration in Bright Gamma-ray Bursts with
Observations of Fermi
Gamma-ray bursts (GRBs) are widely suggested as potential sources of ultrahigh-energy cosmic rays (UHECRs). The kinetic energy of the jets dissipates, leading to the production of an enormous amount of $\gamma$-ray photons and possibly also the acceleration of protons. The accelerated protons will interact with the radiation of the GRB …
