✦ Synopsis

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(αtαs) and are calculated in the Feynman-diagrammatic approach. In the numerical analysis we investigate the variation of M H ± as a function of MA, tan β and the Higgs mixing parameter μ. The two-loop corrections can change M H ± up to 5 GeV for positive values μ and large tan β.
