Higher spin currents in orthogonal Wolf space

For the N = 4 superconformal coset theory by SO(N + 4)/SO(N) x SU (2) x U (1) (that contains an orthogonal Wolf space) with N = 4, the N = 2 WZW affine current algebra is obtained. The 16 generators (or 11 generators) of the large N = 4 linear (or nonlinear) superconformal algebra are described by these WZW affine currents explicitly. Along the line of large N = 4 holography, the extra 16 currents with spins (2, 5/2, 5/2, 3), (5/2, 3, 3, 7/2), (5/2, 3, 3, 7/2), and (3, 7/2, 7/2, 4) are obtained in terms of the WZW affine currents. The lowest spin of this N = 4 multiplet is two rather than one, which is for a unitary Wolf space. The operator product expansions between the above 11 currents and these extra 16 higher spin currents are found explicitly.
