Gamma ray bursts (GRBs) have been proposed as one possible class of sources of the ultrahigh energy cosmic ray (UHECR) events observed up to energies ≳ 1020 eV. The synchrotron radiation of the highest energy protons accelerated within the GRB source should produce gamma rays up to TeV energies. Here we briefly discuss the implications on the energetics of the GRB from the point of view of the detectability of the prompt TeV γ-rays of proton-synchrotron origin in GRBs in the up-coming ICECUBE…

### High-Energy Particles from γ-Ray Bursts

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

It has recently been proposed that ultra-high-energy (≳1019 eV) cosmic rays (UHECRs) are accelerated by the blast waves associated with GRBs. We calculate the observed synchrotron spectrum from

### GEV PHOTONS FROM ULTRAHIGH ENERGY COSMIC RAYS ACCELERATED IN GAMMA RAY BURSTS

Gamma-ray bursts are produced by the dissipation of the kinetic energy of a highly relativistic fireball, via the formation of a collisionless shock. When this happens, Ultra High Energy Cosmic Rays

### The Acceleration of Ultra--High-Energy Cosmic Rays in Gamma-Ray Bursts

UHECRs are roughly isotropic and attain very large energies, $E \gtrsim 3\times 10~{20} \; eV$. Conventional models fail to explain both facts. I show here that acceleration of UHECRs in GRBs

A search made for TeV counterparts to GRBs observed by BATSE detected 54 GRBs within the field of view of Milagrito, and an excess of events coincident in time and space with one of these bursts, GRB 970417a, was observed by Milaghetti.

A search for gamma-ray bursts (GRBs) above 20 TeV within the field of view (1 sr) of the HEGRA AIROBICC Cherenkov array (29N, 18W, 2200 m a.s.l.) has been performed using data taken between March

A scenario in which the highest energy cosmic rays (CR's) and cosmological-ray bursts (GRB's) have a common origin is discussed, consistent with the observed CR flux above 1${0}^{20}$ eV.
