Description

We present a new determination of nuclear Parton Distributions Functions (PDFs) from a number of new processes that constrain the nuclear gluons: single jet and dijet cross-sections from ATLAS and CMS, direct photon production from ATLAS, and charm production by LHC. We use NNLO perturbative QCD calculations for all processes included in the fit. The proton baseline, which nNNPDF3.0 reduces to in the limit A=1, is a variant of the upcoming global NNPDF4.0 determination of proton PDFs, which includes several processes constraining the gluon PDF. We also present an impact study of the upcoming Electron-Ion collider pseudo-data on unpolarized proton and nuclear PDFs determined by a sequential global analysis of inclusive cross sections for lepton-proton and lepton-nucleus Deep-Inelastic Scattering (DIS) pseudo-data.
