Single Top Quark Production with and without a Higgs Boson

One way to probe new physics beyond standard model is to check the correlation among higher dimension operators in effective field theory. We examine the strong correlation between the processes of $pp\to tHq$ and $pp\to tq$ which both depend on the same three operators. The correlation indicates that, according to the data of $pp\to tq$, ${\sigma }_{tHq}=[106.8\pm 64.8]\mathrm{f}\mathrm{b}$ which is far below the current upper limit ${\sigma }_{tHq}\le 900\mathrm{f}\mathrm{b}$.
