Kavli Affiliate: Robert M. Wald | First 5 Authors: Mark G. Klehfoth, Robert M. Wald, , , | Summary: For Euclidean quantum field theories, Holland and Hollands have shown operator product expansion (OPE) coefficients satisfy "flow equations": For interaction parameter $lambda$, the partial derivative of any OPE coefficient with respect to $lambda$ is given by […]
