Longitudinal Polarized Parton Densities Updated
read the original abstract
We have re-analyzed the world data on inclusive polarized DIS, in both NLO and LO QCD, including the new HERMES and COMPASS data. The updated NLO polarized densities are given in both the $\rm \bar{MS}$ and JET schemes. The impact of the new data on the results is discussed.

NNLO Determination of Polarized Parton Distribution Functions with Higher-Twist and Target-Mass Corrections
KLS26 is an NNLO polarized PDF set from inclusive DIS that includes TMC, additive and multiplicative higher-twist terms, and positivity, with the largest NNLO shifts in the strange-quark helicity distribution.

Global analyses of helicity-dependent parton distribution functions
Modern global QCD analyses agree that up-quark helicity is positive and down-quark helicity negative, with positive gluon polarisation at moderate x, while the full gluon spin moment remains limited by the unmeasured ...
