NNLO anomalous dimension matrix for twist-two flavor-singlet operators
Conformal symmetry of QCD is restored at the Wilson-Fisher critical point in noninteger 4−2ϵ space-time dimensions. Correlation functions of multiplicatively renormalizable operators with different anomalous dimensions at the critical point vanish identically. We show that this property allows one t...
