TeV-scale seesaw from a multi-Higgs model [PDF]

open access: yesThe 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.

New tools for dissecting the general 2HDM

open access: yesJournal of High Energy Physics, 2023
Two Higgs doublet models (2HDM) provide the low energy effective theory (EFT) description in many well motivated extensions of the Standard Model. It is therefore relevant to study their properties, as well as the theoretical constraints on these models.

On the Higgs mass fine-tuning problem with multi-Higgs doublet models [PDF]

open access: yesInternational Journal of Modern Physics A, 2018
With no conclusive signal till date of the minimal supersymmetric and extra-dimensional models at the Large Hadron Collider (LHC), the issue of naturalness of the Higgs mass still calls for attention.

Conditions for the custodial symmetry in multi-Higgs-doublet models [PDF]

open access: yesJournal of High Energy Physics, 2018
We derive basis-independent, necessary and sufficient conditions for the custodial symmetry in N-Higgs-doublet models (NHDM) for N ≥ 3, and apply them on some 3HDM examples.

Tree-Level Vacuum Stability in Multi Higgs Models [PDF]

open access: yesProceedings 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 ...

Work Versus Force: Simultaneous Processes for Describing Interactions

open access: yesAdvanced Physics Research, EarlyView.
ABSTRACT Achieving a unified description of interactions remains an open challenge in theoretical physics, which currently describes four fundamental forces. This situation may be viewed differently when interactions are formulated in terms of processes (work as actio) rather than forces (force as actio), not only at the macroscopic level but also at ...

Symmetries in multi-Higgs-doublet models

open access: yes, 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.

Multi‐Omic Profiling Reveals Immune Cell Priming Signature Linked to Lupus Prognosis

open access: yesArthritis &Rheumatology, EarlyView.
Objective Systemic lupus erythematosus (SLE) is a multiorgan disease with widespread immune dysregulation and significant unmet clinical need. Blood‐based gene expression studies have advanced our understanding of SLE pathogenesis but may overlook critical tissue‐specific mechanisms that drive disease heterogeneity and progression.

Nullification of multi-Higgs threshold amplitudes in the standard model [PDF]

open access: yesPhysics Letters B, 1993
We show that nullification of all tree-order threshold amplitudes involving Higgs particles in the Standard Model occurs, provided that certain equations relating the masses of all existing elementary particles to the mass of the Higgs scalar are satisfied.
