Electroweak Physics [PDF]

open access: yes, 2002
The status of precision electroweak measurements as of summer 2002 is reviewed. The recent results on the anomalous magnetic moment of the muon and on neutrino-nucleon scattering are discussed. Precision results on the electroweak interaction obtained by

An effective field theory approach for electroweak interactions in the high energy limit

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
We present an effective action for the electroweak sector of the standard model valid for the calculation of scattering amplitudes in the high energy (Regge) limit.

Measurement of the cross section for electroweak production of a Z boson, a photon and two jets in proton-proton collisions at s $$ \sqrt{\mathrm{s}} $$ = 13 TeV and constraints on anomalous quartic couplings

open access: yesJournal of High Energy Physics, 2020
A measurement is presented of the cross section for electroweak production of a Z boson and a photon in association with two jets (Zγjj) in proton-proton collisions.

TeV scale Dark Matter and electroweak radiative corrections [PDF]

open access: yes, 2010
Recent anomalies in cosmic rays data, namely from the PAMELA collaboration, can be interpreted in terms of TeV scale decaying/annihilating Dark Matter.

Magnetic field instability in a neutron star driven by the electroweak electron-nucleon interaction versus the chiral magnetic effect [PDF]

open access: yes, 2014
We show that the Standard Model electroweak interaction of ultrarelativistic electrons with nucleons ($eN$ interaction) in a neutron star (NS) permeated by a seed large-scale helical magnetic field provides its growth up to $\gtrsim 10^{15}\thinspace ...

Theory of Z boson decays [PDF]

open access: yes, 1999
The precision data on Z boson decays from LEP-I and SLC colliders are compared with the predictions based on the Minimal Standard Theory. The Born approximation of the theory is based on three most accurately known observables: G_mu -- the four fermion ...

Test of lepton universality in beauty-quark decays [PDF]

open access: yesNature Physics, 2021
The standard model of particle physics currently provides our best description of fundamental particles and their interactions. The theory predicts that the different charged leptons, the electron, muon and tau, have identical electroweak interaction ...

Radiative corrections to decay branching ratios of the CP-odd Higgs boson in two Higgs doublet models

open access: yesNuclear Physics B, 2023
We calculate radiative corrections to decay rates of CP-odd Higgs boson A for various decay modes in the four types of two Higgs doublet models with the softly broken discrete Z2 symmetry.

Probing anomalous off-shell electroweak dipole moment of the top quark

open access: yesEPJ Web of Conferences, 2017
A possibility to search for anomalous Wtb interaction ∂μWμ−b¯ f W L P L + f W R P R t is considered for the first time. Despite such couplings do not contribute to both pair top quark production or three main electroweak production ...
