Description

Dark matter annihilations of into 3 body final states are usually neglected in the computation of the dark matter abundance. It has however been recently shown that those kind of processes can significantly affect its relic density. I will focus on the Inert Doublet Model, which is a minimal extension of the standard Model including a weakly interacting scalar dark matter candidate, the inert Higgs. The latter is directly coupled to the standard Higgs and gauge bosons, while having no direct coupling to quarks or leptons. It represent an archetype for WIMP scalar dark matter, with interesting candidates and phenomenology in the GeV and TeV range. I will present a new vision of the viable parameter space of the model once taking into account annihilations into three-body final states which were not included in the previous analysis. I will show the modifications appearing the predicted relic abundance of the inert Higgs as well as in the prospects for direct and indirect detection.
