Three-point functions in N=2 higher-spin holography

The CPN Kazama-Suzuki models with the non-linear chiral algebra SW infinity [lambda] have been conjectured to be dual to the fully supersymmetric Prokushkin-Vasiliev theory of higher-spin gauge fields coupled to two massive N = 2 multiplets on AdS(3). We perform a non-trivial check of this duality by computing three-point functions containing one higher-spin gauge field for arbitrary spin s and deformation parameter A from the bulk theory, and from the boundary using a free ghost system based on the linear sw(infinity)[lambda] algebra. We find an exact match between the two computations. In the 't Hooft limit, the three-point functions only depend on the wedge subalgebra shs[lambda] and the results are equivalent for any theory with such a subalgebra. In the process we also find the emergence of N = 2 superconformal symmetry near the AdS(3) boundary by computing holographic OPE's, consistently with a. recent analysis of asymptotic symmetries of higher-spin supergravity.
