Bound State Effects on Dark Matter Annihilation
Abstract: I will discuss the non-perturbative effects due to dark matter bound states and their strong impact on dark matter searches. I will illustrate this point using three examples. First, I will discuss two dark sector models where the dark matter interacts through a vector or the Higgs portal, and the bound state channels allow indirect detection to explore a much wider range of the parameter space. In the third model, I will include bound state effects in the dark matter relic abundance calculation when it co-annihilates with a top/bottom quark partner, and discuss the implications for direct detection and collider search.
