“…Without introducing the fermions, we can have the supersymmetric version of (1.1) by considering the special value of the level k. This is because we can realize the various spin-1 currents in terms of fermions. For example, see also[16][17][18][19][20][21][22][23][24][25][26][27][28][29] 4. The OPE between G + and G − does not produce the standard N = 2 superconformal algebra for generic M > 1 because the first order pole of this OPE has the additional terms.…”

In the $${{\mathcal {N}}}=2$$ N = 2 supersymmetric coset model, $$\frac{SU(N+M)_k \times SO(2 N M)_1}{ SU(N)_{k+M} \times U(1)_{ N M (N+M)(k+N+M)}}$$ S U ( N + M ) k × S O ( 2 N M ) 1 S U ( N ) k + M × U ( 1 ) N M ( N + M ) ( k + N + M ) , we construct the SU(M) nonsinglet $${{\mathcal {N}}}=2$$ N = 2 multiplet of spins $$(1, \frac{3}{2}, \frac{3}{2}, 2)$$ ( 1 , 3 2 , 3 2 , 2 ) in terms of coset fields. The next SU(M) singlet and nonsinglet $${{\mathcal {N}}}=2$$ N = 2 multiplets of spins $$(2, \frac{5}{2}, \frac{5}{2}, 3)$$ ( 2 , 5 2 , 5 2 , 3 ) are determined by applying the $${{\mathcal {N}}}=2$$ N = 2 supersymmetry currents of spin $$\frac{3}{2}$$ 3 2 to the bosonic singlet and nonsinglet currents of spin 3 in the bosonic coset model. We also obtain the operator product expansions (OPEs) between the currents of the $${{\mathcal {N}}}=2$$ N = 2 superconformal algebra and above three kinds of $${{\mathcal {N}}}=2$$ N = 2 multiplets. These currents in two dimensions play the role of the asymptotic symmetry, as the generators of $${{\mathcal {N}}}=2$$ N = 2 “rectangular W-algebra”, of the $$M \times M$$ M × M matrix generalization of $$\mathcal{N}=2$$ N = 2 $$AdS_3$$ A d S 3 higher spin theory in the bulk. The structure constants in the right hand sides of these OPEs are dependent on the three parameters k, N and M explicitly. Moreover, the OPEs between SU(M) nonsinglet $${{\mathcal {N}}}=2$$ N = 2 multiplet of spins $$(1, \frac{3}{2}, \frac{3}{2}, 2)$$ ( 1 , 3 2 , 3 2 , 2 ) and itself are analyzed in detail. The complete OPE between the lowest component of the SU(M) singlet $${{\mathcal {N}}}=2$$ N = 2 multiplet of spins $$(2, \frac{5}{2}, \frac{5}{2}, 3)$$ ( 2 , 5 2 , 5 2 , 3 ) and itself is described. In particular, when $$M=2$$ M = 2 , it is known that the above $${{\mathcal {N}}}=2$$ N = 2 supersymmetric coset model provides the realization of the extension of the large $${{\mathcal {N}}}=4$$ N = 4 nonlinear superconformal algebra. We determine the currents of the large $${{\mathcal {N}}}=4$$ N = 4 nonlinear superconformal algebra and the higher spin-$$\frac{3}{2}, 2$$ 3 2 , 2 currents of the lowest $${{\mathcal {N}}}=4$$ N = 4 multiplet for generic k and N in terms of the coset fields. For the remaining higher spin-$$\frac{5}{2},3$$ 5 2 , 3 currents of the lowest $$\mathcal{N}=4$$ N = 4 multiplet, some of the results are given.

Some of the operator product expansions (OPEs) between the lowest SO(4) singlet higher spin-2 multiplet of spins (2, 5 2 , 5 2 , 5 2 , 5 2 , 3, 3, 3, 3, 3, 3, 7 2 , 7 2 , 7 2 , 7 2 , 4) in an extension of the large N = 4 (non)linear superconformal algebra were constructed in the N = 4 superconformal coset SO(N +4) SO(N)×SO(4) theory with N = 4 previously. In this paper, by rewriting the above OPEs with N = 5, the remaining undetermined OPEs are completely determined. There exist additional SO(4) singlet higher spin-2 multiplet, six SO(4) adjoint higher spin-3 multiplets, four SO(4) vector higher spin-7 2 multiplets, SO(4) singlet higher spin-4 multiplet and four SO(4) vector higher spin-9 2 multiplets in the right hand side of these OPEs. Furthermore, by introducing the arbitrary coefficients in front of the composite fields in the right hand sides of the above complete 136 OPEs, the complete structures of the above OPEs are obtained by using various Jacobi identities for generic N. Finally, we describe them as one single N = 4 super OPE between the above lowest SO(4) singlet higher spin-2 multiplet in the N = 4 superspace.

The $$ \mathcal{N} $$ = 4 higher spin algebra for generic μ parameter

The $$ \mathcal{N} $$ N = 4 higher spin generators for general superspin s in terms of oscillators in the matrix generalization of AdS3 Vasiliev higher spin theory at nonzero μ (which is equivalent to the ’t Hooft-like coupling constant λ) were found previously. In this paper, by computing the (anti)commutators between these $$ \mathcal{N} $$ N = 4 higher spin generators for low spins s1 and s2 (s1 + s2 ≤ 11) explicitly, we determine the complete $$ \mathcal{N} $$ N = 4 higher spin algebra for generic μ. The three kinds of structure constants contain the linear combination of two different generalized hypergeometric functions. These structure constants remain the same under the transformation μ ↔ (1 − μ) up to signs. We have checked that the above $$ \mathcal{N} $$ N = 4 higher spin algebra contains the $$ \mathcal{N} $$ N = 2 higher spin algebra, as a subalgebra, found by Fradkin and Linetsky some time ago.
