We present a recently developed method to constrain the anomalous dimension of scalar operators in a general Conformal Field Theory (CFT). Using a consistency condition derived from four-point correlation functions it is possible to bind the anomalous dimension of a composite operator φ{symbol}2.

Abstract
We present a recently developed method to constrain the anomalous dimension of scalar operators in a general Conformal Field Theory (CFT). Using a consistency condition derived from four-point correlation functions it is possible to bind the anomalous dimension of a composite operator φ{symbol}2. The result has also consequences on model building. © 2009 Elsevier B.V. All rights reserved.File in questo prodotto:
