In many theoretical models, the observed matter-antimatter asymmetry originates from out-of-equilibrium decays and scatterings of heavy particles. In these scenarios, charge-parity (CP) symmetry violation arises perturbatively through the interference between tree-level and one-loop diagrams. As a result, the CP asymmetry, characterized by the parameter $\epsilon$, is suppresed by higher...
