Description

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 mt < mH + mb and √(s) < 2mH, so that t→ bH+ and e+e- → H+H- are not allowed kinematically. Depending on tan β and mH, the corrections can be of either sign. For large tan β, they lead to a dramatic reduction of the cross section, by more than 50%. (orig.)
