Description

One-loop QCD corrections to the full gauge invariant set of electroweak diagrams describing the charged current processes $e^+ e^- \to u \bar d μ\barν_μ$ (CC10), $e^+ e^- \to u \bar d e^- \barν_e$ (CC20) and $e^+ e^- \to u \bar d s \bar c$ (CC11) 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 corrections for NLC physics.
