Description
We consider N=1 supersymmetric gauge theories in the conformal window. 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
Δa≡aUV−aIR for the N=1 theory. The structure of Δa is therefore in
one-to-one correspondence with the Wess-Zumino dilaton action.
