Abstract
We study a mechanism that generates the baryon asymmetry of the Universe during a tachyonic electroweak phase transition. We utilize as sole source of CP violation an operator that was recently obtained from the Standard Model by integrating out the quarks.

Moreover, recent analytical work [ref] and numerical simulations have indicated that in such a cold environment, Standard Model CP-violation is much larger than at electroweak temperatures and is indeed strong enough to account for the baryon asymmetry [ref] .
