Asymmetric dark matter from semi-annihilation: unitarity constraints and long-lived final states
Tomáš Blažek, Peter Maták, Viktor Zaujec
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 t…

Dirac leptogenesis from asymmetry wash-in via scatterings
Tomáš Blažek, Julian Heeck, Jan Heisig +2
Leptogenesis typically requires the introduction of heavy particles whose out-of-equilibrium decays are essential for generating a matter-antimatter asymmetry, according to one of…
