Abstract

In the framework of spin-0 s-channel dark matter (DM) simplified models, we reassess the sensitivity of future LHC runs to the production of DM in association with top quarks. We consider two different missing transverse energy (E T miss ) signatures, namely production of DM in association with either a \( t\overline{t} \) pair or a top quark and a W boson, where the latter channel has not been the focus of a dedicated analysis prior to this work. Final states with two leptons are studied and a realistic analysis strategy is developed that simultaneously takes into account both channels. Compared to other existing search strategies the proposed combination of \( t\overline{t}+{E}_T^{\mathrm{miss}} \) and tW + E T miss production provides a significantly improved coverage of the parameter space of spin-0 s-channel DM simplified models.
