Antiprotons from spallations of cosmic rays on interstellar matter
نویسنده
چکیده
Cosmic ray antiprotons provide an important probe for the study of the galactic Dark Matter, as they could be produced by neutralino annihilations, primordial black holes evaporations or other exotic sources. On the other hand, antiprotons are anyway produced by standard nuclear reactions of cosmic ray nuclei on interstellar matter (spallations), that are known to occur in the Galaxy. This process is responsible for a background flux that must be carefully determined to estimate the detectability of an hypothetical exotic signal. infn post–doctoral Fellow

Detailed analysis of observed antiprotons in cosmic rays
In the present work, the origin of antiprotons observed in cosmic rays (above the atmosphere) is analyzed in details. We have considered the origin of the primaries, (which their interactions with the interstellar medium is one of the most important sources of antiprotons) is a supernova type II then used a diffusion model for their propagation. We have used the latest parameterization for anti...
متن کاملProduction of antimatter in the galaxy
The astronomical dark matter could be made of weakly interacting massive species whose mutual annihilations should produce antimatter particles and distortions in the corresponding energy spectra. The propagation of cosmic rays inside the Milky Way plays a crucial role and is briefly presented. The uncertainties in its description lead to considerable variations in the predicted primary fluxes....
متن کاملThe Science of Pamela Space Mission
Many different mechanisms can contribute to antiprotons and positrons production, ranging from conventional reactions up to exotic processes like neu-tralino annihilation. The open problems are so fundamental (i.e.: is the universe symmetric in matter and antimatter ?) that experiments in this field will probably be of the greatest interest in the next years. Here we will summarize the present ...
متن کاملCosmic antiprotons as a probe for neutralino dark matter?
The flux of cosmic ray antiprotons from neutralino annihilations in the galactic halo is computed for a large sample of models in the Minimal Supersymmetric extension of the Standard Model. We also revisit the problem of estimating the background of low-energy cosmic ray induced secondary antiprotons, taking into account their subsequent interactions (and energy loss) and the presence of nuclei...
متن کاملGalactic cosmic rays & gamma rays : a synthesis
We have developed a model which aims to reproduce observational data of many kinds related to cosmic-ray origin and propagation: direct measurements of nuclei, antiprotons, electrons and positrons, γ-rays, and synchrotron radiation. Our main results include evaluation of diffusion/convection and reacceleration models, estimates of the halo size, calculations of the interstellar positron and ant...
