摘要：
We review the numerical effects of the leading two-loop corrections to the mass of the charged Higgs boson, M-H +/-, in the MSSM. They consist of the contributions of O(alpha(t)alpha(s)) and are calculated in the Feynman-diagrammatic approach. In the numerical analysis we investigate the variation of M-H +/- as a function of M-A, tan beta and the Higgs mixing parameter mu. The two-loop corrections can change M-H +/- up to 5 GeV for positive values mu and large tan beta.
