Description
Relevant constraints and selected phenomenological implications of a
class of two Higgs doublet models where flavour-changing neutral
currents (FCNC) couplings are suppressed by small entries of the mixing
matrix are analysed. This property of the considered models is the
result of a discrete symmetry of the Lagrangian such that the FCNC are
completely fixed, in the quark sector, by the CKM mixing matrix V and
the ratio of the vacuum expectation values of the neutral Higgs.
Extending it to the leptonic sector introduces FCNC controlled by the
PMNS mixing matrix. The analysis involves a significant number of
processes which include tree and loop level transitions mediated by a
charged and/or neutral Higgses. The new physical scalars, i.e. beyond
the standard Higgs boson, can have masses within experimental reach.
