Flavour Expedition to the Zeptouniverse

Abstract

After the completion of the Standard Model (SM) through the Higgs discovery, particle physicists are waiting for the discovery of new particles either directly with the help of the Large Hadron Collider (LHC) or indirectly through quantum fluctuations causing certain rare processes to occur at different rates than predicted by the SM. While the latter route is very challenging, requiring very precise theory and experiment, it allows a much higher resolution of short distance scales than it is possible with the help of the LHC. In fact, in the coming flavour precision era, in which the accuracy of the measurements of rare processes and of the relevant lattice QCD calculations will be significantly increased, there is a good chance that we may get an insight into the scales as short as 10^{-21} m (Zeptouniverse) corresponding to energy scale of 200 TeV or even shorter distance scales. In particular, we emphasize the correlations between flavour observables as a powerful tool for the distinction between various New Physics models. We will summarize the present status of deviations from SM predictions for a number of flavour observables and list prime candidates for new particles responsible for these anomalies. A short outlook for coming years will be given.
