Structure-dependent QED in B − → ℓ − ν ¯ γ $$ {B}^{-}\to {\ell}^{-}\overline{\nu}\left(\gamma \right) $$

Journal of High Energy Physics
Based on explicitly gauge invariant interpolating operators we compute complete next-leading order QED-corrections for leptonic decays. These are sizeable since the helicity-suppression in V-A interactions allows for structure-dependent collinear logs ...

Combining QED and approximate ${\rm N}^3$LO QCD corrections in a global PDF fit: MSHT20qed_an3lo PDFs

SciPost Physics
We present the MSHT20qed_an3lo parton distribution functions (PDFs). These result from the first global PDF analysis to combine QED and approximate $N^3$LO (a$N^3$LO) QCD corrections in the theoretical calculation of the PDF evolution and cross sections ...

The photon content of the neutron

Journal of High Energy Physics
In this work, we complete our CT18qed study with the neutron’s photon parton distribution function (PDF), which is essential for the nucleus scattering phenomenology. Two methods, CT18lux and CT18qed, based on the LUXqed formalism and the DGLAP evolution,

Relativistic recoil as a key to the fine-structure puzzle in muonic 90Zr

Communications Physics
Muonic atoms provide one of the most sensitive probes of nuclear charge distributions and stringent tests of bound-state quantum electrodynamics (QED).

Possible precision measurements of Delbrück scattering with high flux polarized gamma-ray sources

, 2022
Quantum electrodynamics (QED), which describes the interaction of photons with electrons, has been tested experimentally and found to agree with experiments to high precision to lowest order.

Analytical solution for QCD $$\otimes $$ ⊗ QED evolution

European Physical Journal C: Particles and Fields
We present an analytical solution for the evolution of parton distributions incorporating mixed-order QCD $$\otimes $$ ⊗ QED corrections, addressing both polarized and unpolarized cases.

High precision tests of QED and physics beyond the standard model

, 2020
. We study the four most significant high precision observables of QED -the anomalous electron and muon magnetic moments, the hydrogen Lamb shift and muonium hyperfine splitting-in the context of SU (2) ⊗ U (1) gauge-invariant effective Lagrangians.

QED $\otimes$ QCD Threshold Corrections at the LHC

, 2004
We use the theory of YFS resummation to compute the size of the expected resummed soft radiative threshold effects in precision studies of heavy particle production at the LHC, where accuracies of 1 percent are desired in some processes. We find that the

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}_{{
