Abstract
We consider heavy quark contributions to the polarized Bjorken sum rule. We found good agreement be-tween the experimental data and the predictions of analytic QCD. To satisfy the limit of photoproduction, weuse new representation of the perturbative part of the polarized Bjorken sum rule, recently proposed.
