We use the nCTEQ analysis framework to investigate nuclear parton distribution functions (nPDFs) in region of large $x$ and intermediate-to-low $Q$, with special attention recent JLab deep inelastic scattering data on targets. This lies a which is often excluded by $W$ $Q$ cuts global nPDF analyses. As we relax these cuts, enter new kinematic region, introduces phenomenology. In particular, study impact (i) target mass corrections, (ii) higher twist (iii) deuteron (iv) shape PDF...
We extend the QCD Parton Model analysis using a factorized nuclear structure model incorporating individual nucleons and pairs of correlated nucleons. Our high-energy data from lepton deep-inelastic scattering, Drell-Yan, W Z boson production simultaneously extracts universal effective distribution quarks gluons inside nucleon pairs, their nucleus-specific fractions. Such successful extraction these distributions marks significant advance in our understanding properties connecting nucleon-...
We discuss the two most recent global analyses of nuclear parton distribution functions within nCTEQ approach. LHC data on $W/Z$-boson, single-inclusive hadron and heavy quark/quarkonium production are shown to not only significantly reduce gluon uncertainty down $x\geq10^{-5}$, but also influence strange quark density. The latter is further constrained by neutrino deep-inelastic scattering charm dimuon data, whose consistency with neutral-current experiments re-evaluated.
