Single top quark production at the Fermilab Tevatron Run II (a p \bar{p} collider with \sqrt{S} = 2 TeV) proceeds dominantly via two sub-processes, a t-channel W-gluon fusion process, and an s-channel W^* process. We show that these two…

We show that the production rate of the single-top quark event from the $W$-gluon fusion process is sensitive to new physics which strongly modifies the interactions of the top quark. The measurement of its production rate gives the partial…
