Two-Loop Contributions of the Order Osαt) to the Masses of the NMSSM Higgs BosonsMargarete Mühlleitner1, Heidi Rzehak2, Nhung Thi Dao1, and •Kathrin Walz11Institute for Theoretical Physics, Karlsruhe Institute of Technology — 2Physikalisches Institut, Albert-Ludwigs-Universität Freiburg

The Higgs sector of the Next-to Minimal Supersymmetric Extension of the Standard Model features five neutral Higgs bosons. Compared to the MSSM it is extended by one additional complex singlet field.

After the discovery of a Higgs-like boson at the LHC it is important to have accurate phenomenological predictions available for the different models in order to discuss them in light of the experimental results.

We contribute to this effort by calculating the two-loop contributions of the order Osαt) in the approximation of vanishing external momentum to the masses of the neutral Higgs bosons in the framework of the NMSSM. We employ a renormalization scheme that mixes on-shell and DR renormalization conditions matching those we used in our previous one-loop calculation.
