The Effective Description of Strong Electroweak Symmetry Breaking

open access: yes, 2010
The actual mechanism of electroweak symmetry breaking remains the last unsolved part of the Standard model of electroweak interactions. We review the general requirements that all possible solutions must fulfill.

Constraining the Natural MSSM through tunneling to color-breaking vacua at zero and non-zero temperature

open access: yesPhysics Letters B, 2014
We re-evaluate the constraints on the parameter space of the minimal supersymmetric standard model from tunneling to charge- and/or color-breaking minima, taking into account thermal corrections.

Visible GeV ALP from TeV Vector‐Like Leptons

open access: yesFortschritte der Physik, Volume 73, Issue 3, March 2025.
Abstract A model is presented where a GeV axion‐like‐particle (ALP) is predicted in a large portion of the parameter space due to the presence of explicit Peccei–Quinn (PQ) symmetry‐breaking terms in an exotic leptonic sector. The latter provides a solution to the muon g−2$g-2$ anomaly, within the framework of the Linear Seesaw neutrino mechanism.

Measurement of the effective leptonic weak mixing angle

open access: yesJournal of High Energy Physics
Using pp collision data at s $$ \sqrt{s} $$ = 13 TeV, recorded by the LHCb experiment between 2016 and 2018 and corresponding to an integrated luminosity of 5.4 fb −1, the forward-backward asymmetry in the pp → Z/γ * → μ + μ − process is measured.

Studies of Parity Violation in Atoms

open access: yesAnnalen der Physik, Volume 537, Issue 2, February 2025.
This article provides an overview of atomic parity violation (APV), emphasizing its role in testing the Standard Model and probing new physics. The review discusses manifestations of APV, including nuclear‐spin‐independent and dependent effects, and explores isotopic comparison as a method for precision measurements.

Existence of finite-energy electroweak monopoles [PDF]

open access: yes, 2009
Finite-energy electroweak monopoles have important physical applications in the phenomenology of electroweak interaction. In this paper, we establish the existence and uniqueness of such monopoles by a dynamical shooting method and obtain sharp ...

Fractals and Chaotic Solitons Phenomena in Conformable Coupled Higgs System

open access: yesDiscrete Dynamics in Nature and Society, Volume 2025, Issue 1, 2025.
The current study aims to construct and examine a new plethora of soliton solutions for the conformable coupled Higgs system (CCHS), a system of nonlinear fractional partial differential equations (NFPDEs) which was initially presented utilize a systematic structure to consider the responsive mechanism of the Higgs system in the electroweak theory ...

Flavor in SU(5)$SU(5)$ Finite Grand Unified Models

open access: yesFortschritte der Physik, Volume 72, Issue 12, December 2024.
Abstract Four SU(5)N=1$SU(5) \nobreakspace N=1$ supersymmetric models which exhibit S3$S_3$ and/or ZN$Z_N$ symmetries are studied, that are finite to two or all loops, and their corresponding mass matrices. The first is an all‐loop finite model based on an S3×Z3×Z2$S_3\times Z_3\times Z_2$ flavor symmetry, which leads to phenomenologically nonviable ...
