Abstract

Collider experiments provide an opportunity to shed light on dark matter (DM) self-interactions. In this work, we study the possibility of generating DM bound states—the Darkonium—at the LHC and discuss how the annihilation decay of the Darkonium produces force carriers. We focus on two popular scenarios that contain large DM self-couplings: the Higgsinos in the λ−SUSY model and the self-interacting DM (SIDM) framework. After forming bound states, the DM particles annihilate into force mediators, which decay into the standard model particles either through a prompt or displaced process. This generates interesting signals for the heavy resonance search. We calculate the production rate of bound states and study the projected future constraints from the existing heavy resonance searches.

  55. The derivatives in the operator do not cause any suppression of decay width, since the typical momentum of decay products is comparable to DM mass. One can also consider the scenario where the mediator is a vector boson, such as light dark photons. However, the decay in that case suffers additional suppressions from the dark photon mass due to the Landau-Yang theorem. Since the collider study is similar to the scalar channel, we do not consider it in this work.
