The project on heavy flavour physics embraces a major direction ofresearch that will be under investigation at the Institute of Theoretical Physics at theUniversity of Bern. The research plan can be divided into two parts which contain the following subprojects: 1. Precision calculations in the standard modelA) B -> X_s gamma gamma at NLL precision in the SMB) New analysis of the branching ratio for B -> X_s gamma in the SM at NNLL precision 2. Phenomenological analysis in the minimal supersymmetric standard modelC) SQCD corrections to electroweak contributions to b -> s gamma in the unconstained MSSMD) The MSSM in the decoupling limit: A generic Two-Higgs-Doublet ModelE) Complete analysis of the MSSM flavour-structureThe goal of the first part is the precise calculation of the standardmodel contributions to these flavour-changing neutral current (FCNC) processes. This is important in order to identify possible new physics contributions. The second part aims on a better understanding of the flavour-structure of the minimal supersymmetric standard model (MSSM). On the one hand, this limits the allowed parameter-space of the MSSM which gives important constraints for model building. On the other hand one can correlate the MSSM predictions for rare decays and judge whether the MSSM could explain possible deviations from the SM predictions.
