Abstract
We present the results of a global QCD analysis of helicity parton distribution functions (PDFs) that includes the latest polarized W-lepton production data from the STAR collaboration at the Relativistic Heavy-Ion Collider (RHIC). This data allows the first extraction of a nonzero helicity light-quark sea asymmetry within a simultaneous global QCD analysis of unpolarized and helicity PDFs.

Report
Global QCD analysis of helicity parton distribution functions (PDFs) including the latest polarized W -lepton production data from the STAR collaboration presented. It is very important and shows the first extraction of a nonzero helicity light-quark sea asymmetry within a simultaneous global QCD analysis of unpolarized and helicity PDFs.
The paper is very well written and I recommend this for publication.
