Threshold meson production and cosmic ray transport
An interesting accident of nature is that the peak of the cosmic ray spectrum, for both protons and heavier nuclei, occurs near the pion production threshold. The Boltzmann transport equation contains a term which is the cosmic ray flux multiplied by the cross section. Therefore when considering pion and kaon production from proton-proton reactions, small cross sections at low energy can be as ...
متن کامل0 Meson Mixing and Dilepton Production in Heavy Ion Collisions
We study the possibility of ρ − a0 mixing via N-N excitations in dense nuclear matter. This mixing is found to induce a peak in the dilepton spectra at an invariant mass equal to that of the a0. We calculate the cross section for dilepton production through mixing and we compare its size with that of π − π annihilation. In-medium masses and mixing angles are also calculated. Some preliminary re...
متن کاملGamma-ray Production in Supernova Remnants
Supernova remnants are widely believed to be a principal source of galactic cosmic rays, produced by diffusive shock acceleration in the environs of the remnant’s expanding shock. This review discusses recent modelling of how such energetic particles can produce gamma-rays via interactions with the remnants’ ambient interstellar medium, specifically via neutral pion decay, bremsstrahlung and in...
متن کاملGamma–ray Production in Supernova Remnants
The bulk of the cosmic rays up to about 100 TeV are thought to be accelerated by the 1st order Fermi mechanism at supernova shocks, producing a power-law spectrum. Both electrons and protons should be accelerated, but their ratio on acceleration is not well known. Recently, the EGRET instrument on the Compton Gamma Ray Observatory has observed supernova remnants IC 443 and γ Cygni at GeV energi...
متن کاملNumerical Models for Cosmic Ray Propagation and Gamma Ray Production
An extensive program for the calculation of galactic cosmic-ray propagation has been developed. Primary and secondary nucleons, primary and secondary electrons, and secondary positrons are included. The basic spatial propagation mechanisms are (momentum-dependent) diffusion, convection, while in momentum space energy loss and diffusive reacceleration are treated. Fragmentation and energy losses...
