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

Theoretical Summary, Electroweak Physics [PDF]

open access: yesarXiv, 1999
Aspects of theoretical electroweak physics are summarized, including the status of electroweak radiative corrections, the hadronic contribution to the running of alpha, global fits to precision data and their implication for testing the standard model and constraining new physics, and electroweak baryogenesis.

Could a Gamma Line Betray the Mass of Light Dark Matter? [PDF]

open access: yesDans 2007 Electroweak Interactions and Unified Theories - Electroweak Interactions and Unified Theories, La Thuile : Italie (2007), 2007
We compute the pair annihilation cross section of light dark matter scalar particles into two photons, and discuss the detectability of the monochromatic line associated with these annihilations.

Electroweak monopoles and electroweak baryogenesis [PDF]

open access: yesarXiv, 2018
We describe electroweak monopoles within the Born-Infeld extension of $SU(2)_L\times U(1)_Y$ electroweak theory. We argue for topological stability of these monopoles and computed their mass in terms of the Born-Infeld mass parameters. We then propose a new mechanism for electroweak baryogenesis which takes advantage of the following salient features ...

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 electroweak-induced production of Wγ with two jets in pp collisions at s = 8 $$ \sqrt{s}=8 $$ TeV and constraints on anomalous quartic gauge couplings

open access: yesJournal of High Energy Physics, 2017
A measurement of electroweak-induced production of Wγ and two jets is performed, where the W boson decays leptonically. The data used in the analysis correspond to an integrated luminosity of 19.7 fb−1 collected by the CMS experiment in s = 8 $$ \sqrt{s}=
