摘要：Radiative corrections in the MSSM involving non-vanishing CP-phases can induce mixing between the CP-even and the CP-odd states. In particular, the lightest Higgs boson is not purely CP-even but receives a CP-odd component. Results are presented for the leading two-loop contributions of O(atas) to the masses in the Higgs sector of the MSSM with non-vanishing CPphases. They are derived in the Feynman-diagrammatic approach using on-shell renormalization and contain besides the leading logarithmic also subleading and non-logarithmic corrections.
