The Coset Spin-4 Casimir Operator and Its Three-Point Functions with Scalars
Changhyun Ahn
We find the GKO coset construction of the dimension 4 Casimir operator that contains the quartic WZW currents contracted with completely symmetric SU(N) invariant tensors of ranks…

The Large N 't Hooft Limit of Coset Minimal Models
Changhyun Ahn
Recently, Gaberdiel and Gopakumar proposed that the two-dimensional WA_{N-1} minimal model conformal field theory in the large N 't Hooft limit is dual to the higher spin theories…
