The strongly interacting electroweak phase transition [PDF]

Nuclear Physics B, 1995
A quantitative discussion of nonperturbative effects for the high temperature electroweak phase transition is presented. We propose a method for the computation of the temperature dependent effective scalar potential that takes into account the running of the effective gauge coupling.

Studies of Parity Violation in Atoms

Annalen 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.

Electroweak baryogenesis with vector-like leptons and scalar singlets

Journal of High Energy Physics, 2019
We investigate the viability of electroweak baryogenesis in a model with a first order electroweak phase transition induced by the addition of two gauge singlet scalars.

Top quark electroweak interactions

, 2021
I discuss how modified EW interactions lead to energy growth in $2\to 2$ scattering amplitudes and how the framework of the Standard Model Effective Field Theory can be used in conjunction with the Goldstone boson equivalence theorem to better understand the origin of such unitarity violating behaviour.

Vector condensate model of electroweak interactions [PDF]

The European Physical Journal C, 2004
In the standard model of electroweak interactions the Higgs doublet is replaced by a complex vector doublet and a real vector singlet. The gauge symmetry is broken dynamically by a mixed condensate of the doublet and singlet vector fields. Gauge fields get their usual standard model masses by condensation. The new vector matter fields become massive by

Fractals and Chaotic Solitons Phenomena in Conformable Coupled Higgs System

Discrete 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

Fortschritte 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 ...

Electroweak Interaction Model with an Undegenerate Double Symmetry

Symmetry, Integrability and Geometry: Methods and Applications, 2006
The initial P-invariance of the electroweak interaction Lagrangian together with the low-energy results of the Weinberg-Salam model is provided by a local secondary symmetry.

How to Experimentally Determine the Influence of the Weak Nuclear Force in Promoting Molecular Chirality via Heavy–Metal Promoted Autocatalytic Synthesis of Amino Acids

ChemistrySelect, Volume 9, Issue 36, September 25, 2024.
An experimental test of the impact of the parity non‐conserving weak nuclear interaction on the chirality of a nascent chiral carbon center is proposed. It is shown that catalysis by heavy elements could yield observable chiral preferences within a time span of weeks to months when heavy metals are used to promote amino acid synthesis via an ...

Electroweak observables in neutrino-electron scattering from a muon storage ring

Journal of High Energy Physics
We investigate the sensitivity of a companion neutrino detector situated in the plane of a high-energy, high-intensity muon storage ring to elastic ν μ and ν e scattering on electrons (EνES). Assuming a muon collider with center-of-mass energies of up to
