Cosmological Gamma-Ray Bursts and the Highest Energy Cosmic Rays
We discuss a scenario in which the highest energy cosmic rays (CR's) and cosmological $\ensuremath{\gamma}$-ray bursts (GRB's) have a common origin. This scenario is consistent with the observed CR flux above 1${0}^{20}$ eV, provided that each burst produces similar energies in $\ensuremath{\gamma}$ rays and in CR's above 1${0}^{20}$ eV. Protons …
