摘要：

We incorporate QCD corrections into the calculation of signals for charged Higgs bosons produced in t-quark decays at the tevatron energy, in the leading-log approximation. We find that the signal in the 2-tau channel is enhanced by up to a factor of three in the region tan beta-less-than-or-similar-to 1, essentially closing this window where a light charged Higgs might escape discovery. The signal is reduced somewhat for large tan beta, but remains viable there.
