Momentum dependent two-loop contributions to the neutral CP-even Higgs boson masses in the rMSSM — •Sophia Borowka, Gudrun Heinrich, and Wolfgang Hollik — Max-Planck-Institut für Physik, München

One of the main uncertainties remaining in the calculation of the Higgs boson masses in the real MSSM with public codes like FeynHiggs stem from the missing momentum dependent contributions at the two loop level. In this talk the exact momentum dependent two-loop corrections of order Os αt) to the neutral CP-even MSSM Higgs boson masses are presented. Some integrals which are not available in fully analytical form posed a bottleneck in previous calculations. We solved this problem by using the program SecDec 2.1 to compute two-loop topologies with up to four different mass scales numerically.
