We consider $$\mathcal{N}=1$$ supersymmetric gauge theories in the conformal window.
effective action, by Komargodski and Schwimmer, to rederive the difference of the Euler anomaly coefficient $\Delta a = a_{UV} – a_{IR}$
for the $$\mathcal{N}=1$$ theory thereby rederiving a well-known result.
The structure of $\Delta a$ is therefore in one-to-one correspondence with the Wess-Zumino dilaton term.
