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.

Yukawa alignment in a multi Higgs doublet model: An effective approach [PDF]
Physics Letters B, 2011 In the two Higgs doublet model, natural flavour conservation can be achieved through the use of a discrete Z2 symmetry. A less restrictive condition is the requirement of alignment in the Yukawa sector. So far, alignment has been an anzatz, not rooted in a specific model.

Symmetries in multi-Higgs-doublet models
, 2012 We report the recent progress in understanding of symmetries which can be implemented in the scalar sector of electroweak symmetry breaking models with several Higgs doublets. In particular we present the list of finite reparametrization symmetry groups which can appear in the three-Higgs-doublet models.

Tree-Level Vacuum Stability in Multi Higgs Models [PDF]
Proceedings of International Europhysics Conference on High Energy Physics — PoS(HEP2005), 2007 In the most general model with two Higgs doublets, if a minimum that preserves the $U(1)_{em}$ symmetry exists, then charge breaking (CB) minima cannot occur. The depth of the potential at a stationary point that breaks CB or CP, relative to the $U(1)_{em}$ preserving minimum, is proportional to the squared mass of the charged or pseudoscalar Higgs ...

TeV-scale seesaw from a multi-Higgs model [PDF]
The European Physical Journal C, 2010 We suggest new simple model of generating tiny neutrino masses through a TeV-scale seesaw mechanism without requiring tiny Yukawa couplings. This model is a simple extension of the standard model by introducing extra one Higgs singlet, and one Higgs doublet with a tiny vacuum expectation value.
