QED corrections to the evolution of parton distributions
read the original abstract
We study the systematic inclusion of QED corrections in the evolution of parton distributions. O(alpha) corrections modify the evolution equation for parton distributions. They introduce additional parton distributions, like the photon distribution in the nucleon, and lead to additional mixing effects. We discuss the modifications for a realistic model of N_f,up up-type flavours and N_f,down down-type flavours. We have implemented these corrections into a numerical program and we quantify the size of these effects in a toy model. The corrections reach the order of 1%.

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.
