Adler function, Bjorken Sum Rule and Crewther-Broadhurst-Kataev relation with generic fermion representations at order O ( α$_{s}$ $^{4}$ )
Abstract:
We compute the nonsinglet Adler D-function and the coefficient function for Bjorken polarized sum rules S$^{Bjp}$ at order O ( α$_{s}$ $^{4}$ ) in an extended QCD model with arbitrary number of fermion representations. The Crewther-Broadhurst-Kataev (CBK) relation in this order is confirmed.
