Informal HET Seminar - IAS - Boaz Keren-Zur, Ecole Polytechnique Federale de Lausanne, CH -The Local Callan-Symanzik Equation: Structure & Application

Wed, Sep 11, 2013, 1:30 pm to 2:30 pm
Bloomberg Lecture Hall - Institute for Advanced Study
The local Callan-Symanzik equation describes the response of a quantum field theory to local scale transformations in the presence of background sources. The consistency conditions associated with this anomalous equation can be used to derive powerful constraints on RG flows. We will discuss various aspects of the equation and present new results regarding the structure of the anomaly. We then use the equation to write correlation functions of the trace of the energy-momentum tensor off-criticality.
