Predicting the Higgs Mass in the MSSM

It is known that in contrast to the Standard Model, the mass of the lightest Higgs boson can be predicted in the Minimal Supersymmetric Standard Model (MSSM). While it is bounded from above by the mass of the Z boson at tree level, it acquires sizeable radiative corrections and thus can reach 125 GeV at higher orders. In this talk I will present an overview of different methods for Higgs mass calculations in the MSSM (fixed order, Effective Field Theory), their advantages, drawbacks and current status. Next, I will show how recent improvements in Higgs mass calculations can change the allowed parameter space of supersymmetric models, using the CMSSM, AMSB and the pMSSM11 as examples.
