Reconstruction and Selection of Single Top + Higgs to $\mathrm{b}\overline{\mathrm{b}}$ events at CMS in pp Collisions at $\sqrt{s}$ = 13 TeV

Abstract

The associated production of a single top quark together with a Higgs boson at the LHC can be used to lift the degeneracy regarding the sign of the top quark Yukawa coupling. Therefore, t-channel and tW-channel production where the Higgs boson is decaying into a $\mathrm{b}\overline{\mathrm{b}}$ pair is inspected. Boosted decision trees are used to assign jets to the quarks in the final state and classify the events. To maximize the separation between the signal and the dominating $\mathrm{t}\overline{\mathrm{t}}$ background each event is reconstructed under a signal and a $\mathrm{t}\overline{\mathrm{t}}$ hypothesis. The poster focuses on the event selection and the reconstruction of events.
