The full + mass dependence is computed in the case where one of the quarks is + massless and the other one carries the mass M. As applications we + consider the single-top-quark production via the process $q\bar{q}\to + t\bar{b}$ and the decay rate of a charged Higgs into hadrons. + In both cases the computed NLO corrections are shown to be numerically + much less important than the leading ones. + + |**K.G.
