abstract

We propose a factorized approach to QED radiative corrections for inclusive and semi-inclusive deep-inelastic scattering to systematically account for QED and QCD radiation contributions to both processes on equal footing. This is achieved by utilizing factorization to resum logarithmically enhanced QED radiation into universal lepton distribution and fragmentation (or jet) functions. Numerical simulations suggest that the QED effects induced by the rotational distortion of the hadron transverse momentum, arising from the mismatch between the experimental Breit frame and the true photon-hadron frame, can be as large as 50\% for moderate $Q$, and become increasingly important for large transverse momenta. Our framework provides a uniform treatment of radiative effects for extracting three-dimensional hadron structure from high-energy lepton-hadron scattering at current and future facilities, such as the Electron-Ion Collider.

  1. Single inclusive hadron and jet production in lepton-hadron scattering

    hep-ph 2026-07 conditional novelty 7.0 of 10

    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.

  2. Factorized QED and QCD Contribution to Deeply Inelastic Scattering

    hep-ph 2025-05 conditional novelty 7.0 of 10

    The NLO factorized QED contribution to the leading e+q->e+X subprocess of DIS is computed and shown to be infrared safe with no free parameters beyond the factorization scale.

  3. Impact of QED Radiation on SMEFT Constraints in Deep Inelastic Scattering

    hep-ph 2026-07 conditional novelty 6.5 of 10

    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.

  4. QED nuclear medium effects at EIC energies

    nucl-th 2025-02 conditional novelty 5.0 of 10

    QED interactions between electrons and the screened Coulomb field of a lead nucleus produce percent-level corrections to elastic and inclusive deep-inelastic scattering rates at EIC energies.
