Description

This talk summarizes main results of a recent determination of the polarized deeply inelastic parton distributions to NLO from the world data. In the analysis the LO and NLO parton densities and their 1σ statistical errors were derived and parameterized. The strong coupling constant αs(M2Z) is determined: αs(M2Z) = 0.113 ± 0.004 (stat) ± 0.004 (fac) + 0.008/-0.005 (ren). Comparisons of the low moments of the parton densities with recent lattice results are performed
