Abstract
We analyze a noncanonically renormalized theory in dimensions with the aid of normal-product methods. By a systematic use of Callan-Symanzik equations we show how a critical point can be determined and the anomalous scale dimensions of all composite operators obtained by using Wilson's expansion. These methods are also applied to the coefficient distributions appearing in operator-product expansions.
