摘要：

We study the behaviour of Green functions of the energy-momentum tensor under transformations of the conformal group. For the massless phi-4(4)-theory it is shown that only for a unique choice of the improvement parameter are all anomalies expressible by those of dilatations. Otherwise a genuine conformal breaking is also present.
