On Bjorken sum rule with analytic coupling
arXiv:2406.20000
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 photoproduction limit was also considered and a new representation of the perturbative contribution to the polarized Bjorken sum rule was obtained.
