摘要：
Results for the two-loop corrections to the Higgs-boson masses of the MSSM with complex parameters of O(alpha(2)(t) + alpha(t)alpha(b) + alpha(2)(b)) from the Yukawa sector in the gauge-less limit are presented. The corresponding self-energies and their renormalization have been obtained in the Feynman-diagrammatic approach. The impact of the new contributions on the Higgs spectrum is investigated. Furthermore, a comparison with an existing result in the limit of the MSSM with real parameters is carried out. The new results will be included in the public code FeynHiggs.
