Description
The occurence of $CP$-asymmetric processes is one of the necessary conditions for successful matter-antimatter asymmetry generation in the early universe. Considering any initial state, by unitarity and $CPT$ symmetry, the sum of the asymmetries over all possible final states vanishes. In this contribution, we present a diagrammatic approach to simplifying asymmetry calculations and allowing for systematic tracking of their cancelations at any perturbative order. It is based on Phys. Rev. D 103, L091302, and recent developments.
