Query: PDF Flavor Determination and the nCTEQ PDFs   Recent LHC W/Z vector boson production data in proton-lead collisions are
quite sensitive to the heavier flavors (especially the strange PDF), and this
complements the information from neutrino-DIS data. As the proton flavor
determination is dependent on nuclear corrections (from heavy target DIS, for
example), LHC heavy ion measurements can also help improve proton PDFs. We
introduce a new implementation of the nCTEQ code (nCTEQ++) based on C++ which
has a modular strucure and enables us to easily integrate programs such as
HOPPET, APPLgrid, and MCFM. Using ApplGrids generated from MCFM, we use nCTEQ++
to perform a fit including the $pPb$ LHC W/Z vector boson data.
