Correlation functions of just renormalizable tensorial group field theory: The melonic approximation

High Energy Physics - Theory 2015-09-08 v2

Abstract

The DD-colored version of tensor models has been shown to admit a large NN-limit expansion. The leading contributions result from so-called melonic graphs which are dual to the DD-sphere. This is a note about the Schwinger-Dyson equations of the tensorial φ54\varphi^{4}_{5}-model (with propagator 1/p21/{\bf p}^{2}) and their melonic approximation. We derive the master equations for two- and four-point correlation functions and discuss their solution.
