Baryon asymmetry of the Universe from evaporation of primordial black holes

Abstract

The process of baryogenesis through the evaporation of black holes formed at the end of inflation phase is considered. The increase of black hole mass due to accretion from the surrounding radiation after the reheating is taken into account. It is shown that the influence of the accretion on the baryogenesis is important only in the case when the initial values of black hole mass are larger than $\sim 10^{4}g$. The behavior of calculated baryon asymmetry, as a function of model parameters, is studied.
