Abstract: The widely accepted interpretation of the phenomenology of γ-ray bursts (GRBs), bursts of 0.1 MeV-1 MeV photons lasting for a few seconds (see [1] for a review), is that the observable effects are due to the dissipation of the kinetic energy of a relativistically expanding wind, a “fireball,” whose primal cause is not yet known (see [2],[3] for reviews). The recent detection of “afterglows,” delayed low energy (X-ray to radio) emission of GRBs (see [4] for review), confirmed the cosmological origin of the bursts, through the redshift determination of several GRB host-galaxies, and confirmed standard model predictions of afterglows that result from the collision of an expanding fireball with its surrounding medium (see[5] for review). In this review, the production in GRB fireballs of γ-rays, high-energy cosmic-rays and neutrinos is discussed in the light of recent GRB and ultra-high-energy cosmic-ray observations.
