From theory to precision modelling of strong-field QED in the transition regime

Journal of Physics: Conference Series, 2022
Abstract The combination of energetic electron beams, delivered from conventional accelerators at a high repetition rate, and ultraintense lasers, makes it possible to perform precision measurements of strong-field QED. The LUXE collaboration aims to perform precision measurements of nonlinear Compton scattering and Breit-Wheeler pair ...

Power-enhanced leading-logarithmic QED corrections to B q → μ + μ −

Journal of High Energy Physics, 2019
We provide a systematic treatment of the previously discovered power- enhanced QED corrections to the leptonic decay B q → μ + μ − (q = d, s) in the frame- work of soft-collinear effective theory (SCET).

Combined Effect of QCD Resummation and QED Radiative Correction to W boson Observables at the Tevatron

, 2004
A precise determination of the W boson mass at the Fermilab Tevatron requires a theoretical calculation in which the effects of the initial-state multiple soft-gluon emission and the final-state photonic correction are simultaneously included .

Coulomb corrections for coherent neutrino nucleus scattering

Journal of High Energy Physics
In this work we consider sub-leading O(Z 2 α 3) corrections to coherent elastic neutrino nucleus scattering (CEvNS). These corrections are not negligible by power counting since nuclei with large coherent cross sections have sizeable nuclear charges e.g.

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 ...

Novel astrophysical probes of light millicharged fermions through Schwinger pair production

Journal of High Energy Physics, 2019
The extreme properties of neutron stars provide unique opportunities to put constraints on new particles and interactions. In this paper, we point out a few interesting ideas that place constraints on light millicharged fermions, with masses below around

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,

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.
