Abstract

Conformal symmetry of QCD is restored at the Wilson-Fisher critical point in noninteger 4 −2�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 to calculate off-diagonal parts of the anomalous dimension matrices for leading-twist operators from ...
