Description

A search is presented for the production of a Higgs boson in association with a single top quark by the CMS experiment at the LHC at a center-of-mass energy of 13 TeV. The production cross section for this process is highly sensitive to the absolute values of the top quark Yukawa coupling, the Higgs boson coupling to vector bosons, and, uniquely, to their relative sign. Analyses using multilepton signatures, targeting H → WW, H → ττ, and H → ZZ decay modes, and signatures with a single lepton and a bb pair, targeting the H → bb decay, are combined with a reinterpretation of a measurement in the H → γγ channel to constrain the Yukawa coupling. Results from the 2016 dataset, corresponding to an integrated luminosity of 35.9 fb$^{-1}$, will be presented, along with prospects for future measurements.
