The general Two-Higgs Doublet Model in a gauge-invariant form

open access: yesJournal of High Energy Physics, 2022
In the general Two-Higgs Doublet Model it has been shown that the Higgs potential can be expressed in terms of gauge-independent quantities that transform covariantly under unitary mixing of the doublets.

Unitarity bounds on extensions of Higgs sector

open access: yesJournal of High Energy Physics, 2023
It is widely believed that extensions of the minimal Higgs sector is one of the promising directions for resolving many puzzles beyond the Standard Model (SM).

BSM patterns in scalar-sector coupling modifiers

open access: yesJournal of High Energy Physics, 2023
We consider what multiple Higgs interactions may yet reveal about the scalar sector. We estimate the sensitivity of a Feynman topology-templated analysis of weak boson fusion Higgs pair production at present and future colliders — where the signal is a ...

Constraining CP4 3HDM with Top Quark Decays

open access: yesUniverse, 2021
CP4 3HDM is a unique three-Higgs-doublet model equipped with a higher-order CP-symmetry in the scalar and Yukawa sector. Based on a single assumption (the minimal model with a CP-symmetry of order 4 and no accidental symmetry), it leads to a remarkable ...

A precision constraint on multi-Higgs-doublet models [PDF]

open access: yesJournal of Physics G: Nuclear and Particle Physics, 2008
We derive a general expression for Delta rho (or, equivalently, for the oblique parameter T) in the SU(2) x U(1) electroweak model with an arbitrary number of scalar SU(2) doublets, with hypercharge +-1/2, and an arbitrary number of scalar SU(2) singlets.

The mass-degenerate SM-like Higgs and anomaly of (g − 2) μ in μ-term extended NMSSM

open access: yesJournal of High Energy Physics, 2022
We chose the μ-term extended next-to-minimal supersymmetric standard model (μNMSSM) for this work, and we perform a phenomenological study based on the assumption that the observed Standard Model (SM)-like Higgs is explained by the presence of a double ...

Pseudoscalar MSSM Higgs Production at NLO SUSY-QCD

open access: yesJournal of High Energy Physics, 2023
One of the most important mechanisms at the Large Hadron Collider (LHC) for the production of the pseudoscalar Higgs boson of the Minimal Supersymmetric Standard Model (MSSM) is the loop-induced gluon fusion process gg → A.

Minimal flavour violation and multi-Higgs models

open access: yesPhysics 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 ...
