Description
Summary:The light CP even Higgs boson mass, M h , is calculated to three-loop accuracy within the Minimal Supersymmetric Standard Model (MSSM). The result is expressed in terms of parameters and implemented in the computer program H3m . The calculation is based on the proper approximations and their combination in various regions of the parameter space. The three-loop effects to M h are typically of the order of a few hundred MeV and opposite in sign to the two-loop corrections. The remaining theory uncertainty due to higher order perturbative corrections is estimated to be less than 1 GeV.
