Towards the Identification of New Physics through Correlations between Flavour Observables

Abstract

We emphasize the power of correlations between flavour observables in the search for New Physics and identify a number of correlations that could allow to discover New Physics even if it would appear at the level of 20% of the Standard Model contributions. After presenting the simplest correlations in CMFV and U(2)^3 models we address the recent data on B_{s,d}->mu^+ mu^- and the anomalies in B_d -> K^* mu^+ mu^- in the context of Z'-models and SM Z, both with flavour violating neutral couplings. A strategy consisting of twelve steps which concentrate on theoretically clean observables, to be measured in this decade, could one day allow us to reach the Zeptouniverse. The related DNA charts based on the correlations between enhancements and supressions of various observables in a given New Physics scenario relative to the Standard Model predictions allow a transparent distinction between various extensions of this model. The present text is the extended version of the talk to be published in the proceedings of this symposium.
