Description
We present a new global QCD analysis of unpolarized and polarized data, using a Monte Carlo approach to simultaneously extract both the spin-averaged and helicity PDFs. We focus on the light quark sea asymmetries, including new data from the SeaQuest experiment and $W$-lepton production at RHIC. For the first time we extract a nonzero light quark sea asymmetry for the helicity PDFs through a QCD global analysis using the latest data from the STAR collaboration.
