Two-Higgs-doublet model and quark-lepton unification
Journal of High Energy Physics, 2022 We study the Two-Higgs-Doublet Model predicted in the minimal theory for quark-lepton unification that can describe physics at the low scale. We discuss the relations among the different decay widths of the new Higgs bosons and study their phenomenology ...

Unitarity bounds for all symmetry-constrained 3HDMs
Journal of High Energy Physics, 2022 Models with three Higgs doublets (3HDM) are the source of much recent activity, for they are key components of many solutions to the problems of the Standard Model; from extra sources of CP violation to Dark Matter candidates.

Nuclear Physics B, 2015 We study direct searches of additional Higgs bosons in multi-top-quarks events at the LHC Run-II, its luminosity upgraded version with 3000 fb−1, and the International Linear Collider (ILC) with the collision energy of 1 TeV.

Journal of High Energy Physics, 2023 CP violation plays a very important role in nature with implications both for Particle Physics and for Cosmology. Accounting for the observed matter-antimatter asymmetry of the Universe requires the existence of new sources of CP violation beyond the ...

Conditions for the custodial symmetry in multi-Higgs-doublet models [PDF]
Journal of High Energy Physics, 2018 AbstractWe derive basis-independent, necessary and sufficient conditions for the custodial symmetry in N-Higgs-doublet models (NHDM) forN≥ 3, and apply them on some 3HDM examples.

Journal of High Energy PhysicsThe search for double Higgs production in b b ¯ W + W − $$ b\overline{b}{W}^{+}{W}^{-} $$ , where both W bosons decay to leptons, has been rehabilitated as a good option to investigate key processes within the Standard Model scalar sector at the LHC. The

A new avenue to charged Higgs discovery in multi-Higgs models [PDF]
Journal of High Energy Physics, 2014 Current searches for the charged Higgs at the LHC focus only on the $ $, $cs$, and $tb$ final states. Instead, we consider the process $pp\to \to W^\pm H^\mp \to W^+ W^- A$ where $ $ is a heavy neutral Higgs boson, $H^\pm$ is a charged Higgs boson, and $A$ is a light Higgs boson, with mass either below or above the $b\bar{b}$ threshold. The cross-

Journal of High Energy Physics, 2023 The A → Z (*) h decay signature has been highlighted as possibly being the first testable probe of the Standard Model (SM) Higgs boson discovered in 2012 (h) interacting with Higgs companion states, such as those existing in a 2-Higgs Doublet Model (2HDM)

CP-violation in the Weinberg 3HDM potential
Journal of High Energy PhysicsWe explore the phenomenology of Weinberg’s ℤ 2 × ℤ 2 symmetric three-Higgs-doublet potential, allowing for spontaneous violation of CP due to complex vacuum expectation values.

Two Higgs Doublets, a 4th Generation and a 125 GeV Higgs: A Review
Advances in High Energy Physics, 2013 We review the possible role that multi-Higgs models may play in our understanding of the dynamics of a heavy 4th sequential generation of fermions. We describe the underlying ingredients of such models, focusing on two Higgs doublets, and discuss how ...
