Abstract
The anomalous dimension of single and multi-trace composite operators of scalar fields is shown to vanish at all orders of the perturbative series. The proof hold for theories with supersymmetry with any number of hypermultiplets in a generic representation of the gauge group. It then applies to the finite theory as well as to nonconformal models.File in questo prodotto:
