CP-violation for electroweak baryogenesis from dynamical CKM matrix

We show that the CKM matrix can be the source of CP violation for electroweakbaryogenesis if Yukawa couplings vary at the same time as the Higgs acquires its vacuumexpectation value. This offers new avenues for explaining the baryon asymmetry of theuniverse. These ideas apply if the mechanism explaining the flavour structure of the StandardModel is connected to electroweak symmetry breaking. We compute the resulting baryonasymmetry for various low-scale flavour models and different configurations of the Yukawacoupling variation across the bubble wall, and show that it can naturally be of the right order
