Sphalerons, baryogenesis, and helical magnetogenesis in the electroweak transition of the minimal standard model

Abstract

We start by considering the production rates of sphalerons with different sizes ρ in the symmetric phase, T>TEW. At small ρ, the distribution is cut off by the growing mass M∼1/ρ, and at large ρ by the magnetic screening mass. In the broken phase, T
