Next-to-leading order corrections to single top quark production and decay at the Fermilab Tevatron. II.t-channel process

We present a study of the t-channel mode of single top-quark production at the upgraded Tevatron pp̄ collider, including the next-to-leading order quantum chromodynamics corrections to the production and the decay of a single top-quark. The narrow width approximation was adopted in order to preserve the spin of the top-quark in its production and decay. We discuss the effects of different O(αₛ) contributions on the inclusive cross section as well as various kinematic distributions after imposing the relevant cuts to select t-channel single top signal events.
