Three Point Functions in the Large N=4 Holography

Understand

The 16 higher spin currents with spins (1, 3/2, 3/2, 2), (3/2, 2, 2, 5/2), (3/2, 2, 2, 5/2) and (2, 5/2, 5/2, 3) in an extension of large N=4 `nonlinear' superconformal algebra in two dimensions were obtained previously.

• By analyzing the zero mode eigenvalue equations carefully, the three point functions of bosonic (higher spin) currents with two scalars for any finite N (where SU(N+2) is the group of coset) and k (the level of spin-1 Kac Moody current) are obtained.
• Furthermore, the 16 higher spin currents with above spin contents in an extension of large N=4 `linear' superconformal algebra are obtained for generic N and k implicitly.
• The corresponding three point functions are also determined.
