Higgs‐induced screening mechanisms in scalar‐tensor theories

open access: yesAnnals of the New York Academy of Sciences, Volume 1531, Issue 1, Page 95-103, January 2024.
Abstract We consider the theory of a light conformally coupled scalar field, that is, one that is coupled directly to the Ricci scalar of the gravitational sector. This theory can be written equivalently as one of a light scalar that is coupled to the Standard Model of particle physics with a particular combination of Higgs‐portal couplings.

Fate of Electroweak Vacuum during Preheating

open access: yes, 2016
Our electroweak vacuum may be metastable in light of the current experimental data of the Higgs/top quark mass. If this is really the case, high-scale inflation models require a stabilization mechanism of our vacuum during inflation. A possible candidate

Pinning down the gauge boson couplings in WWγ production using forward proton tagging

open access: yesJournal of High Energy Physics, 2020
In this paper, we explore the potential of the LHC to measure the rate of pp → p WWγ p process, also to probe the new effective couplings contributing to the WWγ and WWγγ vertices.

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

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 ...

Differences Between Two Weak Interaction Theories

open access: yesPhysical Science International Journal, 2019
This paper analyzes differences between theoretical elements of the Standard Model electroweak theory and corresponding properties of a dipole-dipole weak interaction theory.
