Higher Spin Currents with Arbitrary N in the N=1 Stringy Coset Minimal Model

Understand

In the N=1 supersymmetric coset model based on (A_{N-1}^{(1)} \oplus A_{N-1}^{(1)}, A_{N-1}^{(1)}) at level (k, N), the lowest N=1 higher spin supercurrent with spins-(5/2, 3), in terms of two independent numerator WZW currents, is reviewed.

• By calculating the operator product expansions (OPE) between this N=1 higher spin supercurrent and itself, the next two N=1 higher spin supercurrents can be generated with spins-(7/2, 4) and (4, 9/2).
• These four currents are polynomials of degree 3, 4, 4, 4 in the first numerator WZW currents with level k.
• The complete nonlinear OPE of the lowest N=1 higher spin supercurrent for general N is obtained.
