Description

The weak-isospin conductivity determines the rate of baryon number violating sphaleron processes in the high temperature phase of the Standard Model and is thus an important input for predictions of the primordial Baryon asymmetry. So far, only electroweak interactions were included in the computation of the conductivity. Presenting work published in 2510.20594, we for the first time also include strong interactions at leading-log accuracy. They decrease the quark contribution to the conductivity and therefore increase the electroweak sphaleron rate.
