A. V. Kotikov, B. G. Shaikhatdenov
TL;DR
This paper analyzes the polarized Bjorken sum rule at low Q2 using perturbative QCD up to NNLO, focusing on twist-two contributions.
Contribution
It provides a detailed perturbative QCD analysis of the Bjorken sum rule at low momentum transfer, including higher-order corrections.
Findings
Perturbative corrections improve the sum rule's theoretical predictions.
Analysis confirms the validity of twist-two approximation at low Q2.
Results suggest potential areas for non-perturbative effects.
Abstract
We study the polarized Bjorken sum rule at low momentum transfer squared Q2<3GeV2 in the twist-two approximation and to the next-to-next-to-leading order accuracy.
