Simulation of a Three‐Nucleons System Transition on Quantum Circuits

open access: yesAdvanced Quantum Technologies, Volume 8, Issue 5, May 2025.
A general procedure is presented to calculate the transition probability for two nuclear states and a transition operator. The ground state is approximated through the variational quantum eigensolver and the first excited one using more sophisticated variational algorithms.

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

open access: yes, 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

open access: yesFortschritte 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.

Precision electroweak physics at the LHeC and FCC-eh [PDF]

open access: yesProceedings of XXV International Workshop on Deep-Inelastic Scattering and Related Subjects — PoS(DIS2017), 2017
Electroweak (EW) physics at the future electron-proton colliders LHeC and FCC-eh is studied. Simulated neutral-current and charged-current deep-inelastic scattering cross sections are employed for simultaneous determinations of the parton distribution functions of the proton together with the fundamental parameters of the EW theory, including ...

Double-pole approximation for leading-order semi-leptonic vector-boson scattering at the LHC

open access: yesJournal of High Energy Physics
Measuring vector-boson scattering beyond the fully-leptonic final state is becoming possible at the LHC, which demands to have a solid control on the theory predictions for all final states of this class of processes.

Studies of Parity Violation in Atoms

open access: yesAnnalen 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.

Oblique corrections in general dark U(1) models

open access: yesJournal of High Energy Physics
We 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 ...

Complementary constraints on Zb b ¯ $$ Zb\overline{b} $$ couplings at the LHC

open access: yesJournal of High Energy Physics, 2023
We propose a new strategy to probe the Z boson couplings to bottom and charm quarks at the LHC. In this work we mainly focus on the case of bottom quarks. Here, the Z boson is produced in association with two b-jets and decays to electrons or muons.

Precision Electroweak Tests of the Standard Model

open access: yes, 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
