Description
The exploitation of the exciting physics program of the Run II of the Large Hadron Collider requires high-precision theoretical calculations, of which the parton distribution functions (PDFs) of the proton are a central ingredient. In this talk we present the new update of the NNPDF family of global analysis, NNPDF3.1. This new PDF set is based on the NNPDF3.0 fitting framework supplemented with a wide variety of new experimental measurements from HERA, Tevatron and the LHC. The list of new datasets includes top-quark pair differential distributions from ATLAS and CMS, the transverse momentum distributions of the Z boson from ATLAS and CMS, the D0 electron and muon W asymmetries from the complete Tevatron dataset, the legacy Run I LHCb measurements of W and Z production in the forward region, and the ATLAS W,Z 2011 inclusive measurements, in addition to several others. Fits both with perturbative charm and with a fitted charm PDF are presented, which are then used for precision studies about the charm content of the proton. We briefly discuss the phenomenological implications of NNPDF3.1 for LHC phenomenology at Run II.
