STXS measurement of topquark-antiquark pair production in association with a Higgs boson at CMS — •Sebastian Wieland1, Ulrich Husemann1, Philip Keicher1, Matthias Schröder2, and Jan van der Linden1 — 1Institut für Experimentelle Teilchenphysik (ETP), Karlsruher Institut für Technologie (KIT) — 2Universität Hamburg
Top quark-antiquark pair production in association with a Higgs boson offers a model-independent measurement of the top-Higgs Yukawa coupling. This is of great interest in order to precisely test the couplings of the Higgs boson to fermions predicted by the standard model. Since physics beyond the Standard Model may show in the spectrum of the transverse momentum of the Higgs boson, a joint effort of Higgs analyses in all channels is made in order to simplify and streamline potential combinations between measurements. In the context of these Simplified Template Cross Section (STXS) measurements the cross section is measured in common bins.
In this talk a multivariate STXS measurement in the semileptonic decay channel of the top quark-antiquark pair and the decay of the Higgs boson into a bottom quark-antiquark pair based on the full Run-2 dataset of the CMS experiment is presented.
