We consider N = 1 supersymmetric gauge theories in the conformal The running of the gauge coupling is absorbed into the metric by applying a suitable matter superfield- and Weyl-transformation. The computation becomes equivalent to one of a free theory in a curved background carrying the information of the renormalisation group flow. We use the techniques of conformal anomaly matching and dilaton effective action, by Komargodski and Schwimmer, to rederive the difference of the Euler anomaly coefficient Delta a = a(UV) - a(IR) for the N = 1 theory. The structure of Delta a is therefore in one-to-one correspondence with the Wess-Zumino dilaton action.
