Description
We present an unbiased global determination of spin-dependent parton distribution functions and their uncertainties using the NNPDF methodology: NNPDFpol1.1. As compared to
our previous determination, NNPDFpol1.0, longitudinally polarized deep-inelastic scattering data are now supplemented with the most recent polarized hadron collider data for inclusive jet and W boson production from STAR and PHENIX experiments at RHIC.
Polarized W production data provide a handle on the polarized quark-antiquark separation,
while inclusive jet production data allow us to substantially improve our determination of the medium- and large-x polarized gluon. We study the phenomenological implications of the NNPDFpol1.1 set, in particular concerning the nucleon spin content.
