500.#.#.a: Astroparticle physics, the fusion of particle physics and astrophysics, has become one of the most successful fields out of many multidisciplinary ventures and presents particle physics with extraordinary opportunities. Astrophysical and cosmological arguments and observations by using the ``heavenly laboratories'' have become part of the main-stream methodology to obtain information on existing or hypothetical elementary particles, their interactions and their observable effects in the universe. The search for the particle nature of dark matter, the neutrino mass and the origin of ultra-high-energy cosmic rays are just a few examples of many common intellectual endeavors of particle physics and astrophysics. Doing particle physics beyond the boundaries of accelerator laboratories,for instance, in space, at the South Pole, underground, in the deep sea, under ice or in the desert of Argentina, will inspire future generations of scientists and the public at large. It is needless to say that, astroparticle physics is and will be the front-line area of research in the coming years. In this context the Physics of Gamma-Ray Busts (GBRs) is really multidisciplinary and is one of the least understood current problem in science. Although we observe about 1 GRB per day, we still do not understand correctly the basic mechanism of the prompt emission process. We also do not know what is the mechanism which is responsible for transport of almost baryon free energy although it is in a astrophysical environment. Even the more fundamental one is the, what type of stars produce GRB in the final stage of their life etc., are poorly understood. So I feel that now it is timely to study the physics of GRBs. In the context of the GRB physics, here we are interested to study the high energy emission e.g. gammas, protons, neutrinos etc. from the prompt phase of the GRB which is believed to be very powerful source for producing these particles. In this respect we would like to study first the production of high energy photons from GRBs which may put constraints on the expected ultra high energy cosmic ray (UHECR) spectrum of protons from these sources. Because leptonic origin of high energy photon can not put constraint on UHECR spectrum. Also production of photon by different mechanism will contribute differently to the luminosity. We are interested to study different emission mechanism during the prompt phase of the GRBs and compare their capabilities and efficiencies for production of high energy gamma rays. We shall also devote to study the effect of pair production, Inverse Compton scattering and resonant Compton process which will put constraint on the threshold behavior of the high energy photons.
