  Vector boson production and neutrino deep-inelastic scattering (DIS) data are
crucial for constraining the strange quark parton distribution function (PDF)
and more generally for flavor decomposition in PDF extractions. We extend the
nCTEQ15 nuclear PDFs (nPDFs) by adding the recent $W$ and $Z$ production data
from the LHC in a global nPDF fit. The new nPDF set, referred to as nCTEQ15WZ,
is used as a starting point for a follow-up study in which we assess the
compatibility of neutrino DIS data with charged lepton DIS data. Specifically,
we re-analyze neutrino DIS data from NuTeV, Chorus, and CDHSW, as well as
dimuon data from CCFR and NuTeV. To scrutinize the level of compatibility,
different kinematic regions of the neutrino data are investigated. Fits to the
neutrino data alone and a preliminary global fit are performed and compared to
nCTEQ15WZ.
