摘　　要：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→tHq and pp tq,which both depend on the same three operators.The correlation indicates that,according to the data of pp→tq,σ_(tHq)=[106.8±64.8]fb,which is significantly below the current upper limitσ_(tHq)≤900 fb.
