A Classification and Analysis of Higgs-flavor Models
Abstract
A classification is given of Higgs-flavor models. In these models, there are several Higgs doublets in an irreducible multiplet RPhi of a non-abelian symmetry GPhi, under which the quarks and leptons do not transform (thus giving minimal flavor-changing for the fermions). It is found that different GPhi and RPhi lead to very distinctive spectra of the extra Higgs doublets, including different numbers of "sequential Higgs" and of "inert Higgs" that could play the role of dark matter, different mass relations, and different patterns of SU(2)L-breaking splittings within the Higgs doublets.
