Investigation of Higgs boson couplings via the production of a single top quark in association with a Higgs boson in the $\text{H}\to \text{b}\bar{\text{b}}$ channel

Abstract

A search for the production of a single top quark in association with a Higgs boson is performed using the decay $\text{H}\to \text{b}\bar{\text{b}}$. The rate of this Higgs production mode is particularly sensitive to the relative sign of the Higgs boson couplings to fermions and bosons. The 2015 pp collisions data at a center-of-mass energy of 13 TeV are analyzed. This poster focuses on the discrimination between signal and background events. Upper limits, determined in the two-dimensional plane spanned by the coupling modifiers of the Higgs boson to top quarks and to vector bosons, are presented.
