QCD corrections to t anti bH"- associated production in e"+e"- annihilation

We calculate the QCD corrections to the cross section of e"+e"- #-># t anti bH"- and its charge-conjugate counterpart within the minimal supersymmetric extension of the Standard Model. This process is particularly important if m_t < m_H + m_b and #sq root#(s) < 2m_H, so that t#-># bH"+ and e"+e"- #-># H"+H"- are not allowed kinematically. Depending on tan #beta# and m_H, the corrections can be of either sign. For large tan #beta#, they lead to a dramatic reduction of the cross section, by more than 50%.
