Contribution: pdf


In this proceeding we present the combination of NNLO QCD and NLO EW corrections to $t \bar t$ distributions, focusing on the effect of the photon PDF. We compare the LUXQED and NNPDF3.0QED PDF sets for specific distributions. We further discuss the effect of the EW corrections with respect to the pure QCD ones including scale and PDF uncertainties for both these PDF sets. We focus on the top-quark pair invariant mass, top-quark transverse momentum for 13 TeV and on the top-quark pair rapidity for 8 TeV.
