Resumen

We present details of study of the polarized Bjorken sum rule Γ ₁_p-nQ²) carried out recently in [1]. Four QCD coupling versions are considered: Perturbative QCD (pQCD) in theMS scheme, Analytic Perturbation Theory, and 2δ and 3δ analytic QCD versions. In contrast to pQCD, these QCD variants do not have Landau singularities at low positive Q ². In general, when 2δ and 3δ QCD coupling is used the fitted curves give the best results.
