Abstract: We study the production of a Standard Model SM Higgs boson in associationwith a single top quark and either a light jet or $W$-boson at the LHC with acenter of mass energy of 14 TeV. Due to the destructive interference of thecontributing SM diagrams, the value of the top Yukawa coupling and the sign ofthe $WWh$ coupling may be probed for Higgs masses above 150 GeV where $WW$ and$ZZ$ are the dominant Higgs decays. We consider Higgs masses of $m {h}=120$,150, 180, and 200 GeV and devise experimental cuts to extract the signal fromSM backgrounds and measure the top Yukawa coupling.
