Atomic Parity Nonconservation: Electroweak Parameters and Nuclear Structure

open access: yes, 1992
There have been suggestions to measure atomic parity nonconservation (PNC) along an isotopic chain, by taking ratios of observables in order to cancel complicated atomic structure effects.

Top Quark Flavor Changing Couplings at a Muon Collider

open access: yesAdvances in High Energy Physics, Volume 2024, Issue 1, 2024.
There is growing interest in the development of a muon collider that would make it possible to produce lepton collisions at energies of several TeV. Among others, there can be significant contributions to electroweak gauge boson, Higgs boson, and top quark physics.

Relaxation of the chiral imbalance in dense matter of a neutron star

open access: yesEPJ Web of Conferences, 2016
Using the quantum field theory methods, we calculate the helicity flip of an electron scattering off protons in dense matter of a neutron star. The influence of the electroweak interaction between electrons and background nucleons on the helicity flip is

A Clifford Algebra Approach to Chiral Symmetry Breaking and Fermion Mass Hierarchies

open access: yes, 2017
We propose a Clifford algebra approach to chiral symmetry breaking and fermion mass hierarchies in the context of composite Higgs bosons. Standard model fermions are represented by algebraic spinors of six-dimensional binary Clifford algebra, while ...

Direct CP Violation from Isospin Symmetry Breaking Effects for the Decay Process B-s→P(V)π0 in PQCD

open access: yesAdvances in High Energy Physics, 2019
We investigate the direct CP violation for the decay process of B-s→P(V)π0 (P,V refer to the pseudoscalar meson and vector meson, resp.) via isospin symmetry breaking effects from the π0-η-η′ mixing mechanism in PQCD factorization approach.

Measurement of the Z boson production cross-section in pp collisions at s $$ \sqrt{s} $$ = 5.02 TeV

open access: yesJournal of High Energy Physics
The first measurement of the Z boson production cross-section at centre-of-mass energy s $$ \sqrt{s} $$ = 5.02 TeV in the forward region is reported, using pp collision data collected by the LHCb experiment in year 2017, corresponding to an integrated ...

Higgs Parity, strong CP and dark matter

open access: yesJournal of High Energy Physics, 2019
An exact spacetime parity replicates the SU(2) × U(1) electroweak interaction, the Higgs boson H, and the matter of the Standard Model. This “Higgs Parity” and the mirror electroweak symmetry are spontaneously broken at scale v ′ = 〈H ′ 〉 ≫ 〈H〉, yielding

Electroweak interactions -- theory

open access: yes, 1996
In the first part of this talk there is given a very brief review of the status of the Standard Model (SM). In the second part I discuss electroweak interactions and physics beyond the SM.
