Asymmetric dark matter from semi-annihilation: unitarity constraints and long-lived final states

Abstract This work presents an asymmetric dark matter model with relic density determined by the freeze-out of asymmetric semi-annihilations into long-lived particles slowly decaying into the Standard Model states. We carefully consider the CPT symmetry and unitarity constraints to the asymmetries e...
