One method of probing new physics beyond the Standard Model is to check the correlation among higher-dimensional operators in the effective field theory. We examine the strong correlation between the processes $pp\rightarrow tHq$ and $pp\rightarrow tq$ , which both depend on the same three operators. The correlation indicates that, according to the data of $pp\rightarrow tq$ , $\sigma_{tHq} = \big[106.8 \pm 64.8\big]\; {\rm fb}$ , which is significantly below the current upper limit $\sigma_{tHq}\leqslant 900\; {\rm fb}$ .
