摘要：

We calculate the next-to-leading QCD corrections to the decay H+ --> udBAR for generic up and down quarks in the final state. A recently developed algorithm for the evaluation of massive two-loop Feynman diagrams is employed to calculate renormalization constants of the charged Higgs boson. The origin and summation of large logarithmic corrections to the decay rate of the top quark into a lighter charged Higgs boson is also explained.
