Description
The coannihilation mechanism plays a crucial role in determining the DM relic abundance in a plethora of new physics models. Recently, a general classification of simplified models for this mechanism has been presented in the Coannihilation codex. In particular, the thermal relic abundance of a pure Standard Model singlet DM candidate can naturally be explained by coannihilation with a new colored partner in the dark sector. In these models direct and indirect detection modes are suppressed, however, LHC probes provide striking signatures. On the one hand, a mediator which connects the DM and its colored partner to the visible sector gives rise to a novel dijet resonance plus missing transverse energy final state. In the case where the mediator lies beyond LHC detection, self-annihilation of the colored partner through its strong interactions solely determines the relic abundance. The major LHC signature then is pair-production of the colored partner leading to jets plus missing transverse energy.
