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 ...

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.

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.

Search for quark contact interactions and extra spatial dimensions using dijet angular distributions in proton–proton collisions at s=8 TeV

open access: yesPhysics Letters B, 2015
A search is presented for quark contact interactions and extra spatial dimensions in proton–proton collisions at s=8 TeV using dijet angular distributions. The search is based on a data set corresponding to an integrated luminosity of 19.7 fb−1 collected

A no-go theorem for non-standard explanations of the $\tau\to K_S\pi\nu_\tau$ CP asymmetry

open access: yesSciPost Physics Proceedings, 2019
A new tensor interaction is the only possibility to explain the $2.8\sigma$ tension observed by the BaBar collaboration in the CP asymmetry in $\tau\to K_S\pi\nu_\tau$ with physics beyond the Standard Model (BSM) realized above the electroweak scale.

The Standard Model of Electroweak Interactions

open access: yes, 1994
Gauge invariance is a powerful tool to determine the dynamics of the electroweak and strong forces. The particle content, structure and symmetries of the Standard Model Lagrangian are discussed. Special emphasis is given to the many phenomenological tests which have established this theoretical framework as the Standard Theory of electroweak ...

Analysis of the Wtb vertex from the measurement of triple-differential angular decay rates of single top quarks produced in the t-channel at s=8 $$ \sqrt{s}=8 $$ TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2017
The electroweak production and subsequent decay of single top quarks in the t-channel is determined by the properties of the Wtb vertex, which can be described by the complex parameters of an effective Lagrangian.
