Stochastic wake, field plasma acceleration in gamma-ray bursts

Gamma-Ray Burst (GRB) emissions are so powerful to strongly influence any surrounding plasma. In this paper, we briefly discuss the possibility that a very intense initial burst of radiation produced by GRBs is the cause of stochastic wake field particle acceleration in a surrounding plasma of moderate density. The stochastic Wake Field Acceleration (WFA) provides an interesting link between GRB engine properties, as emission angle and total energy, and spectral features of the emitted photons. The hypothesis that the prompt GRB emission is produced on a plasma environment energized by the precursor and the application of the relations typical of the WFA to the GRB, provide the understanding of the correlation between the spectral properties and the jet solid angle and the total energy similarly to that suggested by recent empirical relations. If the afterglow is produced in the plasma energized by the photons of the prompt emission by the stochastic WFA a link between the prompt total energy and the achromatic time break is obtained.
