Abstract
We consider single-top-quark production via the weak process q q → t b at hadron colliders. This process may provide the best measurement of the magnitude of the Cabibbo-Kobayashi-Maskawa matrix element V tb . We show that a signal can potentially be observed at the Fermilab Tevatron with 3 fb −1 of integrated luminosity. In contrast, the signal is masked at the CERN Large Hadron Collider by top-quark pair production and single-top-quark production via W-gluon fusion.
