High precision determination of the Q² evolution of the Bjorken sum.

The article discusses the study concerning the determination of the high precision of the Q2 evolution of the Bjorken sum. It outlines the significance of the Bjorken sum rule in the study of intrinsic angular moment. Results of the study cover the partonic and intermediate domains of high Q2 that are appropriate in extracting color polarities and in higher-twist coefficients.
