Global analysis of nuclear PDFs with LHC vector boson, single inclusive hadron and heavy quark data

We discuss the two most recent global analyses of nuclear parton distribution functions within the nCTEQ approach. LHC data on W/Z-boson, single-inclusive hadron and heavy quark/quarkonium production are shown to not only significantly reduce the gluon uncertainty down to x≥10−5, but to also influence the strange quark density. The latter is further constrained by neutrino deep-inelastic scattering and charm dimuon production data, whose consistency with neutral-current experiments is also re-evaluated. peerReviewed
