Heavy Quark Contributions in the Bjorken Sum Rule with Analytic Coupling
We consider heavy quark contributions to the polarized Bjorken sum rule. We found good agreement between the experimental data and the predictions of analytic QCD. To satisfy the limit of photoproduction, we use new representation of the perturbative part of the polarized Bjorken sum rule, recently proposed.
