Higher Spin Currents in the N=1 Stringy Coset Minimal Model
Changhyun Ahn
This study reconsidered the N=1 supersymmetric extension of the W_3 algebra which was studied previously. This extension consists of seven higher spin supercurrents (fourteen highe…
The Operator Product Expansion of the Lowest Higher Spin Current at Finite N
Changhyun Ahn
For the N=2 Kazama-Suzuki(KS) model on CP^3, the lowest higher spin current with spins (2, 5/2, 5/2,3) is obtained from the generalized GKO coset construction. By computing the ope…
The Large N 't Hooft Limit of Kazama-Suzuki Model
Changhyun Ahn
We consider N=2 Kazama-Suzuki model on CP^N=SU(N+1)/SU(N)xU(1). It is known that the N=2 current algebra for the supersymmetric WZW model, at level k, is a nonlinear algebra. The N…
The Primary Spin-4 Casimir Operators in the Holographic SO(N) Coset Minimal Models
Changhyun Ahn
Starting from SO(N) current algebra, we construct two lowest primary higher spin-4 Casimir operators which are quartic in spin-1 fields. For N is odd, one of them corresponds to th…
