The relevance of pp interactions in GRB scenarium |
In this work we study the production of pions and electromagnetic energy from pp collisions. We analyse the work of Fermi 1950, in which he used a statistical approach of the interaction, then we compare it with the data obtained with two Monte Carlo codes, SIBYLL and PITHIA. The new telescopes working in the high energy domain could give us better data, although they do not have yet a good accuracy in the MeV-GeV energy range; for example, the Fermi telescope detected more than 100 photons in the energy range >100 MeV from GRB 080916C. The data of the pp interaction show that the radiation spectrum from the collision has a peak around the rest mass of pions (135 MeV). We are investigating the possibility of high energy photons of GRBs be produced from pp interactions process. |
