Heavy Thermal Relics from Zombie Collisions

10 Mar 2020 Kramer Eric David Kuflik Eric Levi Noam Outmezguine Nadav Joseph Ruderman Joshua T.

We propose a new thermal freezeout mechanism which results in dark matter masses exceeding the unitarity bound by many orders of magnitude, without violating perturbative unitarity or modifying the standard cosmology. The process determining the relic abundance is $\chi \zeta^\dagger \to \zeta \zeta$, where $\chi$ is the dark matter candidate... (read more)
