Description
This project discusses the role of gauged Weyl symmetry in the Local Renormalization Group. In this approach, coupling constants are treated as functions of spacetime coordinates, leading to consequences for the two-dimensional trace anomaly. The gauge field sources a current that is identified with the virial one. In the flat-space limit, such theories exhibit scale invariance but are generally not conformally invariant. The two-point functions of the Energy-Momentum tensor and the divergence of the virial current are computed, and their corresponding Renormalization Group equations are derived. The relationships between these quantities are constrained by the Consistency Conditions and are then expressed in terms of scaling functions.
