Abstract
A search is presented for the production of a Higgs boson in association with a single top quark, based on data collected in 2016 by the CMS experiment at the LHC at a center-of-mass energy of 13 TeV, which corresponds to an integrated luminosity of 35.9 fb − 1 . The production cross section for this process is highly sensitive to the absolute values of the top quark Yukawa coupling, y t ; the Higgs boson coupling to vector bosons, g H VV ; and, uniquely, their relative sign. Analyses using multilepton signatures, targeting H → W W , H → τ τ , and H → Z Z decay modes, and signatures with a single lepton and a b ¯ b pair, targeting the H → b ¯ b decay, are combined with a reinterpretation of a measurement in the H → γ γ channel to constrain y t . For a standard model–like value of g H VV , the data favor positive values of y t and exclude values of y t below about − 0.9 y t SM .
