Boltzmann Boost in Assisted Annihilation
August 02, 2019
Assisted annihilation is a mechanism to generate light dark matter through novel annihilation where two DM and one or more no assister(s) are there in the initial state and two SM or SM-like states are in the final state. We showed that depending on the mass hierarchy between assister and dark matter we can have either a suppression or a boost from a Boltzmann factor in the effective cross-section. This boost helps to achieve the required relic density for a MeV scale dark matter mass.
