Higgs mass prediction in the MSSM based on a combination of fixed-order corrections and resummed bottom and tau contributions — •Ivan Sobolev¹ and Georg Weiglein² — ¹DESY, Hamburg, Germany — ²DESY, Hamburg, Germany

In constrast to the Standard Model (SM) in the Minimal Supersymmetric Standard Model (MSSM) Higgs mass is a predictable quantity. Since radiative corrections are large, a very precise calculation is required to limit the theoretical uncertainty from unknown higher order corrections. In the limit of heavy superparticles radiative corrections to Higgs mass scale logarithmically with the mass of the superparticles. These large logarithms can be resummed by making use of effective field theory. However, in case of light superparticles fixed-order calculations are expected to be more precise. To profit from virtues of both methods they should be combined. This method, known as `hybrid', is known for a while and is implemented in the publicly available code FeynHiggs. Our aim is to apply this method to corrections coming from down-type fermions, especially to tau and bottom corrections. In this talk we report on our progress in implementing this method into the code.
