abstract
We present the first calculation of next-to-leading order (NLO) factorized QED and QCD contributions to the short-distance hard coefficients of inclusive lepton-hadron deep inelastic scattering (DIS) in a joint QED and QCD factorization approach. Unlike the traditional radiative correction approach to handle the collision-induced QED contributions to DIS, QED radiation from all charged leptons and quarks are treated equally, and their collinear sensitivities are systematically factorized into corresponding universal lepton and parton distribution functions. We demonstrate that the NLO factorized QED contribution is completely infrared safe and calculable without the need of any parameters other than the standard factorization scale in the same way as the factorized QCD contribution. We discuss the potential impact of this joint factorization approach on the extraction of partonic information from lepton-hadron DIS.

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.
Simulations of 11 and 22 GeV PVDIS pseudodata indicate potential constraints on low-Q² sin²θ_W and high-x strange quark and d/u PDFs, with strong correlations requiring simultaneous QCD-electroweak analysis.
QCD collinear factorization, DGLAP evolution, and QT resummation, developed via DIS and Drell-Yan, form the calculational foundation for precision electroweak observables and new-physics searches.
