The 1/N expansion is a well established approach to studying interacting fixed points of the renormalization group, and the associated conformal field theories. In this talk, I will review old and new results on the conformal limit of the O(N) (vector) and O(N)3 (tensor) models at large N.
This video was produced by the University of Münster, as part of the workshop From perturbative to non-perturbative QFT.
