"Searching for the effects of physics beyond the Standard Model through flavor"

In this talk I will first focus on two flavour physics quantities for which the experimentally measured values appear to be larger than predicted in the Standard Model, and propose a viable BSM scenario that can accommodate both discrepancies. The discussion will then entail the (in)famous $V_{cb}$-problem which can be describe and explain the possible ways out. In the last part of this talk, time permitting, I will argue that the radiative decays of quarkonia can be valuable for searching peculiar effects of New Physics. In that respect the novel lattice QCD results are particularly handy because the Standard Model amplitudes are fully controlled to high precision and should be matched by experiments.
