Description
If the Standard Model Yukawa couplings varied in the early universe and started with order one values before electroweak symmetry breaking, the CP violation associated with the CKM matrix could be the origin of the matter-antimatter asymmetry. The large effective Yukawa couplings which lead to the enhanced CP violation can also help in achieving a strong first-order electroweak phase transition. In this talk, I will discuss the implementation of dynamical Yukawa couplings in the context of the Froggatt--Nielsen mechanism.
