Factorized QED Contribution to Lepton-Hadron DIS
read the original abstract
We present the first calculation of next-to-leading order (NLO) factorized QED contributions to the short-distance hard coefficients of inclusive lepton-hadron deep inelastic scattering (DIS) in a joint QCD and QED factorization approach. We demonstrate how the joint factorization consistently factorize all perturbative collinear sensitivities of partonic scattering in both QCD and QED into corresponding universal hadron and lepton distribution functions without the need of any parameters other than the standard factorization scale. We discuss the necessary modification to DGLAP-type evolution of the parton and lepton distribution functions in this joint factorization approach. We also discuss the potential impact of this joint factorization approach on the extraction of partonic information from lepton-hadron DIS.

Single inclusive hadron and jet production in lepton-hadron scattering
Single inclusive high-PT hadron and jet production in lepton-hadron scattering is factorized using a joint QCD+QED approach with universal lepton distribution functions, and predictions are given for JLab and EIC energies.

Impact of QED Radiation on SMEFT Constraints in Deep Inelastic Scattering
Collision-induced QED radiation produces O(1) corrections to DIS cross sections but only few-percent shifts in longitudinal electron spin asymmetries, making asymmetries more robust for SMEFT constraints at SoLID and EIC.
