The phenomenological investigation of parton distribution functions (PDFs) based on the “valon” model presented here from the QCD ⊗ QED coupled DGLAP evolution equations in theMellin space. The PDFs are calculated at the next to leading order O(α2 s ) in QCD, and we consider theQEDeffects atO(α);O(ααs ) andO(α2) approximations. We also investigate in detail the phenomenological implications of these PDFs on the partonic luminosities. We conclude that at the region of the large values for the di-lepton’s invariant mass, the luminosity combinations, quark–quark, quark–antiquark and gluon–gluon, get closer to the luminosity involving photons, suggesting possibly non-negligible phenomenological implications due to the photon channel. We Also done a perfect comparison of our results with those obtained by the NNPDF2.3QED set, NNPDF3.1luxQED set and APFEL and there are a nice agreement between them.We demonstrate the necessity of including QED corrections and photon-induced contributions for a correct determination of the parton distribution functions and partonic luminosities.
