Abstract

We present a next-to-leading order perturbative QCD analysis of world data on the spin dependent structure functions g^p₁, gⁿ₁, and g^d₁, including the new experimental information on the Q² dependence of gⁿ₁. Careful attention is paid to the experimental and theoretical uncertainties. The data constrain the first moments of the polarized valence quark distributions, but only qualitatively constrain the polarized sea quark and gluon distributions. The NLO results are used to determine the Q² dependence of the ratio g₁/F₁ and evolve the experimental data to a constant Q² = 5 GeV². We determine the first moments of the polarized structure functions of the proton and neutron and find agreement with the Bjorken sum rule.
