Production of secondary particles in heavy nuclei interactions in supernova remnants

摘要: Abstract Depending on their type, supernova remnants may have ejecta material with high abundance of heavy elements such as carbon or oxygen. In addition, core-collapse supernovae explode in the wind progenitor star that also a elements. Hadronic collisions these enriched media spawn production gamma rays, neutrinos, and secondary electrons spectra cannot be scaled from those calculated for pp collisions, potentially leading to erroneous results. We used Monte-Carlo event generators calculate differential rate particles H, He, C, O nuclei projectiles target material. The cross sections multiplicity are separately computed each 16 combinations projectile target. describe characteristic effects shape normalization various produced.
