Abstract:
A general scheme for calculating critical exponents of an arbitrary system of composite operators mixed by a renormalization procedure is presented using 1/N expansion. Restrictions imposed on the mixing matrix by the conformal invariance are investigated. The anomalous dimensions of all powerlike products of an auxiliary field are calculated up to the second order in 1/N.
