Below, we present a brief review of the recent studies of the polarized Bjorken sum rule for small values of . Our careful analysis reveals an excellent agreement between the experimental data and the predictions recently obtained in the framework of analytic QCD. Well-known perturbative expressions for coupling constant on the contrary lead to a strong difference between these data and turn out to be inapplicable. To estimate calculated phenomenological values, we discussed the photoproduction limit. [ABSTRACT FROM AUTHOR] |
