# A Wilsonian energy-momentum tensor

@article{Rosten2016AWE, title={A Wilsonian energy-momentum tensor}, author={Oliver J. Rosten}, journal={The European Physical Journal C}, year={2016}, volume={78}, pages={1-18} }

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.
