EW corrections to t t distributions: the photon PDF effect
Abstract
In this proceeding we present the impact of the EW corrections on t t distributions focusing on the effect of the photon PDF. We use the NNPDF2.3QED and CT14QED PDF sets, which include the photon PDF. We discuss a detailed comparison between the results obtained from these two PDF sets at NLO QCD+EW accuracy for 13 TeV, focusing on the top-quark pT and the top-quark pair rapidity. We point out the differences between these two PDF sets and we show that the rapidity of the top-quark pair can be used in order to constrain the photon PDF predicted by the NNPDF2.3QED set.
