Critical O(N) models above four dimensions Small-N solutions and stability

We explore O(N) models in dimensions 4<d<6. Specifically, we investigate models of an O(N) vector field coupled to an additional scalar field via a cubic interaction. Recent results in d=6−ε have uncovered an interacting ultraviolet fixed point of the renormalization group (RG) if the number N...
