Rates for non-perturbative processes in hot non-abelian plasma

Abstract

[Talk given at "Continuous Advances in QCD '98."] I give a simple physical picture of why the rate $Γ$ per unit volume of non-perturbative processes in hot non-Abelian plasmas (such as electroweak baryon number violation in the very early universe) depends on coupling as $Γ\sim α^5 T^4 \ln(1/α)$. The logarithmic dependence was recently discovered by Bodeker.
