Single-top-quark production via W-gluon fusion at next-to-leading order
- Department of Physics, University of Illinois, 1110 West Green Street, Urbana, Illinois 61801 (United States)
Single-top-quark production via W-gluon fusion at hadron colliders provides an opportunity to directly probe the charged-current interaction of the top quark. We calculate the next-to-leading-order corrections to this process at the Fermilab Tevatron, the CERN Large Hadron Collider, and DESY HERA. Using a b-quark distribution function to sum collinear logarithms, we show that there are two independent corrections, of order 1/ln(m{sub t}{sup 2}/m{sub b}{sup 2}) and {alpha}{sub s}. This observation is generic to processes involving a perturbatively derived heavy-quark distribution function at an energy scale large compared with the heavy-quark mass. {copyright} {ital 1997} {ital The American Physical Society}
