Description
The production of a Higgs Boson with a single top quark is a channel that allows a direct probe of the top Yukawa coupling. While the SM cross-section for pp > thj is small (approx 70fb) due to destructive interference between the W fusion and top emission diagrams as the integrated luminosity of the LHC increases the signal could be extracted from both hh > gamma gamma and h to b bar{b}.
We will discuss how this process could be sensitive to the sign of the top Yukawa coupling and the effect of a change in sign of tbar{t}h on the overall cross section. Furthermore exploration of the 2HDM allows the inclusion of an additional associated diagram and the possibility of further BSM physics.
