Electromagnetic splitting of quark and pseudoscalar meson masses from dynamical QCD + QED [PDF]

, 2013
Lattice QCD simulations are now reaching a precision where electromagnetic corrections from QED become important. In investigating the effects of SU(3) breaking due to quark mass differences within QCD, a group-theoretical analysis of the mass dependence

Qed Radiative Corrections For Parton Distributions [PDF]

, 2007
I discuss radiative corrections due to the emission of photons from quarks which contribute to deep inelastic lepton--nucleon scattering as well as to pp collisions at high energies.

Amplitude-based IR-improvement in precision LHC/FCC physics [PDF]

We present recent results based on the IR-improvement of unintegrable singularities in the infrared regime via amplitude-based resummation in QED $\times$ QCD $\subset$ SU(2)$_{L} \times$ U$_{1} \times$ SU(3)$_{c}$.

Approaching the double-Heisenberg scaling sensitivity in the Tavis–Cummings model

APL Photonics
The pursuit of quantum-enhanced parameter estimations without the need for nonclassical initial states has long been driven by the goal of achieving experimentally accessible quantum metrology.

QED radiative corrections in inverse beta decay from virtual pions

Journal of High Energy Physics
Inverse beta decay (IBD), ν ¯ e p → e + n γ $$ {\overline{\nu}}_ep\to {e}^{+}n\left(\gamma \right) $$ , is the main detection channel for reactor and supernova antineutrinos. To provide precise IBD cross sections at antineutrino energies E ν ¯ e $$ {E}_{{

QED Corrections to the 4p - 4d Transition Energies of Copperlike Heavy Ions [PDF]

, 2006
Quantum electrodynamic (QED) corrections to 4p-4d transition energies of several copper-like ions with Z = 70-92 are calculated non-perturbatively in strong external fields to all orders in binding corrections.

QED and EW in precision measurements [PDF]

, 2019
Precision physics is an invaluable tool, and it can help in the search of physics beyond the Standard Model. In this contribution I will give a short introduction of the main features of the EW precision physics in the context of the Standard Model and ...

Complete one-loop QED corrections to D s + $$ {D}_s^{+} $$ leptonic decays and impact on the CKM unitarity test

Journal of High Energy Physics
Recently, a violation of the CKM unitarity condition has been reported in the latest charm-meson data with the latest lattice results, once the universal electroweak correction is taken into account.
