Yukawa sector of Multi Higgs Doublet Models in the presence of Abelian
symmetries. Part I    [PDF]

H. Serôdio

A general method for classifying the possible quark models of a multi Higgs doublet model, in the presence of abelian symmetries, is presented. All the possible sets of textures that can be present in a given sector are shown, thus turning the determination of the flavour models into a combinatorial problem. Several symmetry implementations are studied for two and three Higgs doublet models. Some models implementations are explored in great detail, with a particular emphasis on models known as Branco-Grimus-Lavoura (BGL) and Nearest-Neighbour-Interaction (NNI). Several considerations on the flavour changing neutral currents (FCNC) of multi Higgs models are also given.
