Implications of U(2)^3 flavour symmetry for flavour observables
Predictions for future experimental signatures of new physics
Abstract
A natural solution to the hierarchy problem of the Fermi scale motivates signals of New Physics at current and near future experiments. After a critical synthesis of this general motivation, we concentrate our attention on the interplay between LHC searches for new resonances, and precision measurements of both Higgs couplings and flavour violating observables. We do so for i) the Higgs sectors of the NMSSM and MSSM, as paradigmatic examples of theories providing extra scalars, and for ii) CKM-like flavour symmetries, with a focus on U(2)^3. This article is mainly based on several papers by the author, but it also reviews other recent related results. Its goal is to provide a synthetic - yet comprehensive orientation on these subjects, at the dawn of several (ATLAS and CMS, LHCb, NA62 etc.) coming experimental results.
