The oblique parameters provide a convenient way of comparing the predictions of a New Physics Model with $SU(2) \times U(1)$ as its gauge group with those of the Standard Model (SM). The Beyond the Standard Model (BSM) particle content of these New Physics Models must consist of fermions and/or scalars that should preferably be in the representations of the gauge group such that they cannout...
In this talk I will describe the minimal 2HDM with U(1) flavour symmetries which accounts for the observed pattern of quark and lepton masses and mixings. The corresponding phenomenology related to flavour processes in both sectors will also be investigated, as well as the constraints imposed in the parameter space.
In multi-Higgs-doublet models, the simultaneous requirement that (i) CP violation only arises spontaneously, (ii) there are no tree level scalar flavour changing couplings and (iii) the fermion mixing matrix is CP violating, can only be achieved in a very specific way. A general approach on the question is presented stressing new clarifying insights. In the quark sector, that possibility is...
