On Bjorken sum rule: heavy quarks and analytic coupling

arXiv:2501.00456

Abstract

We present the results of [1], where good agreement was obtained between calculations within the framework of analytic QCD and experimental data on polarized Bjorken sum rule. The heavy quark contributions are taken into account.
