Collider Bounds on Indirect Dark Matter Searches: The $WW$ Final State

Understand

We describe an effective theory of interaction between pairs of dark matter particles (denoted $\chi$) and pairs of $W$ bosons.

• Such an interaction could accommodate $\chi\bar{\chi}\rightarrow WW$ processes, which are a major focus of indirect dark matter experiments, as well as $pp \rightarrow W\rightarrow W\chi\bar{\chi}$ processes, which would predict excesses at the LHC in the $W$+MET final-state.
• We reinterpret an ATLAS $W$+MET analysis in the hadronic mode and translate the bounds to the space of indirect detection signals.
• We also reinterpret the $W$+MET analysis in terms of graviton theory through the processes $W\rightarrow WG$ and $Z\rightarrow ZG$ in which $G$ is invisible.
