Impact of inclusive hadron production data on nuclear gluon PDFs

A precise knowledge of nuclear parton distribution functions (nPDFs) is---among other things---important for the unambiguous interpretation hard process data taken in $pA$ and $AA$ collisions at Relativistic Heavy Ion Collider (RHIC) LHC. The available fixed target deep inelastic scattering (DIS) Drell-Yan (DY) lepton pair production mainly constrain light quark distributions. It is hence crucial to include more collider global analyses nPDFs order better pin down different flavors, particular gluon small $x$. To help PDF, we extend nCTEQ15 analysis by including single inclusive hadron (SIH) from RHIC (PHENIX STAR) LHC (ALICE). In addition DIS, DY, SIH datasets, will also $W/Z$ data. As calculation dependent on hadronic fragmentation (FFs), use a variety FFs literature properly estimate this source uncertainty. We study impact these PDFs compare with both nCTEQ15WZ sets. calculations are performed using new implementation nCTEQ code (ncteq++) modified version incnlo, which allows faster precomputed grids. extension represents an important step toward next generation PDFs.
