Symmetries for standard model alignment in multi-Higgs doublet models [PDF]
Physical Review D, 2016 We derive the complete set of continuous maximal symmetries for standard model (SM) alignment that may occur in the tree-level scalar potential of multi-Higgs doublet models, with n>2 Higgs doublets. Our results generalize the symmetries of SM alignment, without decoupling of large mass scales or fine-tuning, previously obtained in the context of ...

LEPTOGENESIS IN MODELS WITH MULTI-HIGGS BOSONS [PDF]
Modern Physics Letters A, 2002 We study the leptogenesis scenario in models with multi-Higgs doublets. It is pointed out that the washing-out process through the effective dimension-five interactions, which has not been taken into account seriously in the conventional scenario, can be effective, and the resultant baryon asymmetry can be exponentially suppressed.

CP violation in multi-Higgs supersymmetric models [PDF]
Nuclear Physics B, 1996 We consider supersymmetric extensions of the standard model with two pairs of Higgs doublets. We study the possibility of spontaneous $CP$ violation in these scenarios and present a model where the origin of $CP$ violation is soft, with all the complex phases in the Lagrangian derived from complex masses and vacuum expectation values (VEVs) of the ...

Minima of multi-Higgs potentials with triplets of Î(3n2) and Î(6n2)
Physics Letters B, 2017 We analyse the minima of scalar potentials for multi-Higgs models where the scalars are arranged as either one triplet or two triplets of the discrete symmetries A4, S4, Î(27), Î(54), as well as Î(3n2) and Î(6n2) with n>3.

Minimal flavour violation and multi-Higgs models
Physics Letters B, 2010 We propose an extension of the hypothesis of Minimal Flavour Violation (MFV) to general multi-Higgs Models without the assumption of Natural Flavour Conservation in the Higgs sector. We study in detail under what conditions the neutral Higgs couplings are only functions of $V_{CKM}$ and propose a MFV expansion for the neutral Higgs couplings to ...

Geometrical CP violation in multi-Higgs models [PDF]
Journal of High Energy Physics, 2012 We introduce several methods to obtain calculable phases with geometrical values that are independent of arbitrary parameters in the scalar potential. These phases depend on the number of scalars and on the order of the discrete non-Abelian group considered.
