CC10 at $\mathcal{O}({\alpha }_s)$: QCD corrections to $e^{+}{e}^{-}\to {\mu }^{-}{\bar{\nu }}_{\mu }u\bar{d}$ at LEP2 and the Next Linear Collider

Abstract

QCD one-loop corrections to the semileptonic process $e^{+}{e}^{-}\to {\mu }^{-}{\bar{\nu }}_{\mu }u\bar{d}$ are computed. We compare the exact calculation with a ``naive'' approach to strong radiative corrections which has been widely used in the literature and discuss the phenomenological relevance of QCD contributions for LEP2 and NLC physics.
