Description
I will first discuss model-independent properties of dilaton effective theory. Using soft theorems a constraint on the operator generating a potential dilaton mass will be derived. As the operator is relevant this indicates that the dilaton can only acquire a mass through explicit symmetry breaking. The results will derived alternatively from the Lagrangian and linked to the improvement term necessary to reproduced the defining
Goldstone current matrix element. I will further show how an infrared fixed point interpretation of gauge theories is compatible with the end of the conformal window. I will show how this interpretation is related and supported by N=1
supersymmetric gauge theories.
