Description
Various asymmetry-generating mechanisms are typically based on underlying reactions, such as decays or scatterings. In this contribution, however, we emphasize the essential role of CP invariants, from which a complete list of asymmetry-generating processes can be systematically derived. As a demonstration, we consider an asymmetric dark matter model based on a discrete $\mathbb{Z}_3$ symmetry. We show that the asymmetry source term receives contributions from asymmetric semi-annihilations. If the final-state particles are long-lived, the dark matter can become almost completely asymmetric. This contribution is based on JHEP 04 (2025) 104.
