Description
In this talk, we present the role of fermions within multi-TeV colored co-annihilation scenarios. The interactions of fermions with dark matter (DM) and co-annihilating particles have the potential to introduce novel decay channels for bound states. However, we emphasize that these same interactions also provide efficient mechanisms for bound state formation (BSF), complementing the traditional BSF process involving the emission of a gauge boson. To corroborate this observation, we introduce a model with Majorana DM coupled to a colored scalar mediator through a Yukawa interaction with a right-handed SM quark. We then highlight that for sufficiently large Yukawa coupling, BSF via quark emission/absorption and mediation predicts the possibility of heavier dark matter masses.
