Abstract:
Currently the prime effort of elementary particle physics is the investigation of the flavour sector of the Standard Model. Flavour-changing neutral current processes of K- and B-mesons are related to the electroweak energy scale and are therefore sensitive to short-distance physics. Within the Standard Model they suffer from several suppression mechanism and provide an ideal laboratory to search for new physics. In my talk I give an overview on the phenomenology of flavour physics including CP violation, meson-antimeson mixing and rare decays. I discuss how current and future measurements are affected by new physics, with emphasis on an extended Higgs sector and supersymmetry.
