Challenges for New Physics in the Flavour Sector

Abstract

In these proceedings I present a personal perspective of the challenges for new physics (NP) searches in the flavour sector. Since the CKM mechanism of flavour violation has been established to a very high precision, we know that physics beyond the Standard Model can only contribute sub-dominantly. Therefore, any realistic model of physics beyond the Standard Model (SM) must respect the stringent constrains from flavour observables like $b\to s\gamma$, $B_s\to {\mu }^{+}{\mu }^{-}$, $\Delta F=2$ processes etc., in a first step. In a second step, it is interesting to ask the question if some deviations from the SM predictions (like the anomalous magnetic moment of the muon or recently observed discrepancies in tauonic $B$ decays or $B\to K^{\ast }{\mu }^{+}{\mu }^{-}$) can be explained by a model of NP without violating bounds from other observables.
