The classical sphaleron transition rate exists and is equal to 1.1( αwT) 4
Abstract
Results of a large scale numerical simulation show that the high temperature Chern-Simons number diffusion rate in the electroweak theory has a classical limit Γ = κ( αwT) 4,where κ = 1.09 ± 0.04 and αw is the weak fine structure constant.
