Search for dark matter in final states with a top quark and missing transverse momentum using new hadronic top quark tagging techniques

A search for dark matter is conducted in events with large missing transverse momentum and a hadronically decaying, boosted top quark. This study is performed using proton-proton collision data at a center-of-mass energy of $\sqrt{s}=13~\mathrm{TeV}$ collected by the CMS detector at the LHC, corresponding to an integrated luminosity of $35.8~\mathrm{fb}^{-1}$. No significant deviations from standard model predictions are observed, and limits are placed on the production of new heavy bosons coupling to dark matter particles.
