The {β}-expansion for Adler function, Bjorken Sum Rule, and the Crewther-Broadhurst-Kataev relation at order O( α s 4 $$ {\alpha}_s^4 $$ )

The {β}-expansion for Adler function, Bjorken Sum Rule, and the Crewther-Broadhurst-Kataev relation at order O( α s 4 $$ {\alpha}_s^4 $$ )

Abstract We derive explicit expressions for the elements of the {β}-expansion for the nonsinglet Adler D A -function and Bjorken polarized sum rules S Bjp in the N4LO using recent results by Chetyrkin for these quantities computed within extended QCD including any number of fermion representations....
