Oblique corrections in general dark U(1) models
Journal of High Energy PhysicsWe investigate the impact of dark Abelian gauge bosons on the electroweak precision measurements at the one-loop level. The dark gauge boson couples to the standard model fermions generally via two kinds of mixing with the electroweak gauge bosons: the ...

Electroweak radiative corrections for collider physics [PDF]
Physics reports, 2019 Current particle phenomenology is characterized by the spectacular agreement of the predictions of the Standard Model of particle physics (SM) with all results from collider experiments and by the absence of significant signals of non-standard physics ...

Precision measurements in electroweak physics and supersymmetry
Nuclear Physics B, 1990 Abstract In the minimal supersymmetric standard model we analyse the radiative corrections to M W , the p -parameter and the lepton asymmetries at the Z 0 pole. We show how the radiative corrections of the standard model with a light Higgs give a lower bound on the corrections in the supersymmetric model.

Studies of Parity Violation in Atoms
Annalen der Physik, Volume 537, Issue 2, February 2025.This article provides an overview of atomic parity violation (APV), emphasizing its role in testing the Standard Model and probing new physics. The review discusses manifestations of APV, including nuclear‐spin‐independent and dependent effects, and explores isotopic comparison as a method for precision measurements.

Journal of High Energy PhysicsIn this paper we explore pp → W ± (ℓ ± ν)γ to O 1 / Λ 4 $$ \mathcal{O}\left(1/{\Lambda}^4\right) $$ in the SMEFT expansion. Calculations to this order are necessary to properly capture SMEFT contributions that grow with energy, as the interference ...

Electroweak precision tests in high-energy diboson processes [PDF]
, 2017 A bstractA promising avenue to perform precision tests of the SM at the LHC is to measure differential cross-sections at high invariant mass, exploiting in this way the growth with the energy of the corrections induced by heavy new physics.

Electroweak precision observables and Higgs-boson signal strengths in the Standard Model and beyond: present and future [PDF]
Journal of High Energy Physics, 2016 We present results from a state-of-the-art fit of electroweak precision observables and Higgs-boson signal-strength measurements performed using 7 and 8 TeV data from the Large Hadron Collider.

Fortschritte der Physik, Volume 73, Issue 1-2, February 2025.Abstract S. Gukov and C. Vafa proposed a characterization of rational N=(1,1)$N=(1,1)$ superconformal field theories (SCFTs) in 1+1$1+1$ dimensions with Ricci‐flat Kähler target spaces in terms of the Hodge structure of the target space, extending an earlier observation by G. Moore.
