A SIMPLIFIED TOP DOWN MODEL FOR COSMIC RAY PARTICLE PRODUCTION
Preview AbstractWe investigate the implications of a minimal top down model on cosmic ray particle production from super heavy vector boson annihilation with subsequent pseudo-scalar boson decay. Super heavy particles are assumed to exist according to a homogeneous distribution. Besides the particle production via decay, the thermal momentum distribution of the initial state as well as expansion effects and cosmic temperature corrections are considered in the context of a Friedmann–Robertson–Walker universe.
