Combination of electroweak and QCD corrections to single W production at the Fermilab Tevatron and the CERN LHC

, 2009
Precision studies of the production of a high-transverse momentum lepton in association with missing energy at hadron colliders require that electroweak and QCD higher-order contributions are simultaneously taken into account in theoretical predictions ...

Visible GeV ALP from TeV Vector‐Like Leptons

Fortschritte der Physik, Volume 73, Issue 3, March 2025.
Abstract A model is presented where a GeV axion‐like‐particle (ALP) is predicted in a large portion of the parameter space due to the presence of explicit Peccei–Quinn (PQ) symmetry‐breaking terms in an exotic leptonic sector. The latter provides a solution to the muon g−2$g-2$ anomaly, within the framework of the Linear Seesaw neutrino mechanism.

A case study of SMEFT O 1 / Λ 4 $$ \mathcal{O}\left(1/{\Lambda}^4\right) $$ effects in diboson processes: pp → W ±(ℓ ± ν)γ

Journal of High Energy Physics
In 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 ...

Energy-peak based method to measure top quark mass via B-hadron decay lengths

Journal of High Energy Physics, 2023
We develop a method for the determination of the top quark mass using the distribution of the decay length of the B-hadrons originating from its decay. This technique is based on our earlier observation regarding the location of the peak of the b quark ...

Precision Electroweak Tests of the Standard Model

, 2004
The study of electron-positron collisions at LEP, together with additional measurements from other experiments, in particular those at SLC and at the Tevatron, has allowed for tests of the electroweak Standard Model with unprecedented accuracy. We review

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.

Triboson production in the SMEFT

Journal of High Energy Physics
We study the production of three electroweak gauge bosons at the LHC, in the effective field theory of the standard model, at dimension six and next-to-leading order in QCD.
