Minimal effective theory for leptogenesis, dark matter, and neutrino masses
Tomas Blazek, Peter Matak, Jan Ramaj +1
We study the phenomenology of choosing a minimal set of effective operators simultaneously generating the dark matter relic density and matter-antimatter asymmetry of the universe.…

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…

Axion Dark Matter from Heavy Quarks
Mohammad Aghaie, Giovanni Armando, Angela Conaci +5
We propose simple scenarios where the observed dark matter abundance arises from decays and scatterings of heavy quarks through freeze-in of an axion-like particle with mass in the…
