Impact of a high SUSY scale in the MSSM and beyond
If you have a question about this talk, please contact Dr Maria Ubiali.
For a long time, the minimal supersymmetric standard model (MSSM) with light masses for the supersymmetric states was considered as the most natural extension of the Standard Model of particle physics. Consequently, a valid approximation was to match the MSSM to the precision measurement directly at the electroweak scale. This approach was also utilized by all dedicated spectrum generators for the MSSM . However, the higher the supersymmetric (SUSY) scale is, the bigger the uncertainties which are introduced by this matching. I explain the recent implementation of a two-scale matching in the SARAH /SPheno framework. In this setup, the running parameters within the SM are calculated at MZ and evaluated up to the SUSY scale, where they are matched to the full model which could either be the MSSM are any other, non-minimal SUSY model. I discuss the phenomenological consequences of this calculation with the focus on the mass of the SM-like Higgs state.
