With the start of the Large Hadron Collider LHC (CERN, Geneva) in September 2008 a new era of elementary particle physics is arising. Most likely, at the LHC signals of physics beyond the Standard Model of particle physics will be discovered. Supersymmetry is one of the most promising extensions of the Standard Model. The search for supersymmetric particles has a very high priority at LHC.The research project “Flavour physics and CP violation in supersymmetric theories” is a joint research project of the University of Vienna (Austria) and the University of Würzburg (Germany). Up to now most studies concerning supersymmetry at future colliders have been performed in the Minimal Supersymmetric Standard Model under the assumption that flavour mixing can be neglected and that R-parity is conserved. The main purpose of the present research project is to explore the flavour sector of supersymmetric extensions of the Standard Model, with and without R-parity conservation. We plan to investigate on the one hand the Minimal Supersymmetric Standard Model with intergenerational mixing in the supersymmetry breaking terms and on the other hand models with R-parity violation. In a systematic study we want to consider the most general case including CP violating phases as well as flavour violating parameters. In order to work out the implications of flavour and CP violating parameters for the determination of the underlying supersymmetric parameters, we are going to analyze in a systematic way production and decay processes of supersymetric particles at colliders. We want to take into account the existing experimental and theoretical constraints for the flavour violating parameters and the constraints from the dark matter density. In spite of the severe restrictions we expect large flavour violating signals in the supersymmetric production and decay processes. Therefore, the results of the research project “Flavour physics and CP violation in supersymmetric theories” will play an important role for the experiments at the LHC and other future colliders.
