On Bjorken sum rule with analytic coupling

TL;DR

This paper demonstrates that calculations within analytic QCD accurately match experimental data on the polarized Bjorken sum rule, introduces a new perturbative representation, and considers the photoproduction limit.

Contribution

It provides a new representation of the perturbative contribution to the polarized Bjorken sum rule and confirms the effectiveness of analytic QCD in describing experimental results.

Findings

Good agreement between analytic QCD calculations and experimental data.

A new representation of the perturbative contribution was developed.

The photoproduction limit was analyzed.

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.
