Single top quark production with and without a Higgs boson *

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