Description

QCD evolution equations in MS-like schemes can be recovered from the same equations in a modified theory, QCD in non-integer d=4−2ϵ dimensions, which enjoys exact scale and conformal invariance at the critical point. Restrictions imposed by the conformal symmetry of the modified theory allow one to obtain complete evolution kernels in integer (physical) dimensions at the given order of perturbation theory from the spectrum of anomalous dimensions added by the calculation of the special conformal anomaly at one order less. We discuss details of calculation of two-loop conformal anomaly.
