Pinning down the large-x gluon with NNLO top-quark pair differential distributions

Abstract:

Top-quark pair production at the LHC is directly sensitive to the gluon PDF at large x. While total cross-section data is already included in several PDF determinations, differential distributions are not, because the corresponding NNLO calculations have become available only recently. In this work we study the impact on the large-x gluon of top-quark pair differential distributions measured by ATLAS and CMS at √ s = 8 TeV. Our analysis, performed in the NNPDF3.0 framework at NNLO accuracy, a...
