A Wilsonian Energy-Momentum Tensor
Published 3 May 2016 in hep-th, cond-mat.stat-mech, and hep-ph | (1605.01055v3)
Abstract: For local conformal field theories, it is shown how to construct an expression for the energy-momentum tensor in terms of a Wilsonian effective Lagrangian. Tracelessness implies a single, unintegrated equation which enforces both the Exact Renormalization Group equation and its partner encoding invariance under special conformal transformations.
