AbstractIn the two-Higgs-doublet model the alignment of the Yukawa flavour matrices of the two scalar doublets guarantees the absence of tree-level flavour-changing neutral couplings. The resulting fermion-scalar interactions are parameterized in terms of three complex parameters zeta(f), leading to a generic Yukawa structure which contains as particular cases all known specific implementations of the model based on Z(2) symmetries. These three complex parameters are potential new sources of CP violation.
