摘要：

This study is dedicated to the description of the polarized Bjorken sum rule, based on recently derived formulas within the analytic QCD approach. To accommodate the photoproduction limit and incorporate the Gerasimov-Drell-Hearn and Burkhardt-Cottingham sum rules, we develop a new representation for the twist-2 part of the Bjorken sum rule. The derived results were applied for processing of experimental data. We observed a good agreement between the experimental data and the predictions from analytic QCD. In contrast, there is a significant discrepancy between these data and the fitting curves within the standard perturbative approach.
