Adler function, Bjorken Sum Rule and Crewther-Broadhurst-Kataev relation with generic fermion representations at order O(αs4)
We compute the nonsinglet Adler D-function and the coefficient function for Bjorken polarized sum rules SBjp at order O(αs4) in an extended QCD model with arbitrary number of fermion representations. The Crewther-Broadhurst-Kataev (CBK) relation in this order is confirmed.
