B Violation in the Hot Standard Model

الأصل · EN

I explain, as simply and pedagogically as I can, recent arguments that the high-temperature baryon number violation rate depends on the electroweak coupling as Γ= # α⁵ T⁴ (up to higher order corrections). This is in contrast to the form Γ= # α⁴ T⁴ that has historically been assumed in discussions of electroweak baryogenesis. I will give a general analysis of the time scale for non-perturbative gauge field fluctuations in hot non-Abelian plasmas.
