Possible large-N fixed points and naturalness for O(N) scalar fields

We try to use scale invariance and the large-N limit to find a non-trivial 4D O(N) scalar field model with controlled UV behavior and naturally light scalar excitations. The principle is to fix interactions by requiring the effective action for spacetime dependent background fields to be finite and...
