  "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, $g_\\mathrm{HVV}$, and, uniquely, to their relative sign. Analyses using multilepton signatures, targeting H$\\to$WW, H$\\to\\tau\\tau$, and H$\\to$ZZ decay modes, and signatures with a single lepton and a $\\mathrm{b\\overline{b}}$ pair, targeting the H$\\to\\mathrm{b\\overline{b}}$ decay, are combined with a reinterpretation of a measurement in the H$\\to\\gamma\\gamma$ channel to constrain $y_\\mathrm{t}$. For a standard model-like value of $g_\\mathrm{HVV}$, the data favor positive values of $y_\\mathrm{t}$ and exclude values of $y_\\mathrm{t}$ below about $-$0.9 $y_\\mathrm{t}^\\mathrm{SM}$.",
