Analyzing the Cosmology and Signals of Pseudo-Dirac Dark Matter

by Mariana Carrillo Gonzalez (Imperial College)




Strong bounds from CMB observations have pushed us away from the standard WIMP picture of dark matter (DM). Nevertheless, a dark matter candidate of thermal origin does not require elastic weak interactions to lead to the observed DM abundance. In fact, the simple appearance of Majorana masses changes the standard picture of WIMP DM.  In this talk, I will present a careful analysis of the cosmological evolution and experimental signals for pseudo-Dirac DM. I will focus on the importance of computing the DM abundance to understand the DM signals and on the complementarity of different searches.
