Slightly broken higher spin symmetry: general structure of correlators

A bstract We explore a class of CFT’s with higher spin currents and charges. Away from the free or N = ? limit non-conservation is governed by operators built out themselves, which deforms algebra charges by, together with, its action on currents. This structure encoded in certain /L -algebra. Under quite general assumptions we construct invariants deformed symmetry, are candidate correlation functions. In particular, show that there finite number independent structures at n -point level. The found to have form reminiscent one-loop exact theory. case Chern-Simons vector models uniqueness implies three-dimensional bosonization duality large- limit.
