Description
Higher order corrections in the MSSM with 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(alpha_t
alpha_s) to the masses and mixing effects in the Higgs sector of the MSSM
with non-vanishing CP-phases. They are derived in the Feynman-diagrammatic
approach using on-shell renormalization.
