Abstract
We discuss how the electrons in relativistic GRB shocks can reach near-equipartition in energy with the protons. We emphasize the non-Fermi origin of such acceleration. We argue that the dynamics of the electrons in the foreshock region and at the shock front plays an important role. We also demonstrate that PIC simulations can directly probe this physics in the regimes relevant to GRBs.
