TL;DR: The authors report the results of the experiment E142 which measured the spin dependent structure function of the neutron, which confirms the fundamental Bjorken sum rule with O({alpha}{sub s}{sup 3}) corrections to within one standard deviation, a major success for perturbative Quantum Chromodynamics.
