Critical long-range vector model in the UV

We study interacting critical UV regime of the long-range O(N) vector model with quartic coupling. Analyzing CFT data within the scope of epsilon- and 1/N-expansion, we collect evidence for the equivalence of this model and the critical IR limit of the cubic model coupled to a generalized free field O(N) vector multiplet.

Automated summary

The study reveals the equivalence between the interacting critical UV regime of the long-range O(N) vector model with quartic coupling and the critical IR limit of the cubic model coupled to a generalized free field O(N) vector multiplet.
