N't Hooft limit and compared to the spectrum of the proposed holographic dual, a 3d higher
spin gravity theory coupled to massive scalar fields. At finite N, the CFT contains additional
light states that are not visible in the perturbative gravity theory. We carefully define the large
N limit, and give evidence that, at N=∞, the additional states become null and decouple from
all correlation functions. The surviving states are shown to match precisely (for all values of …
