Search for associated production of a Higgs boson and a single top quark in proton-proton collisions at root s=13 TeV
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.

| Summary: | 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, yt; the Higgs boson coupling to vector
bosons, gHVV; and, uniquely, 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 yt. For a standard model–like value of gHVV, the data favor positive values of yt and exclude
values of yt below about −0.9yt
