Abstract

The complete $O (α_{s})$ QCD corrections to the decay process $H^{-} \to {\bar{u}}_{i} d_{j}$ of a charged Higgs boson are calculated for an arbitrary up-type quark mass while treating the down-type quark as massless. In the leading-logarithmic approximation, the QCD corrections to the decay rates can be conveniently expressed in terms of the running masses. The corrections decrease the charged-Higgs-boson decay width, as in the case of the standard-theory neutral-Higgs-boson decay.
