An AdS_3 Dual for Minimal Model CFTs

Understand

We propose a duality between the 2d W_N minimal models in the large N 't Hooft limit, and a family of higher spin theories on AdS_3.

• The 2d CFTs can be described as WZW coset models, and include, for N=2, the usual Virasoro unitary series.
• The dual bulk theory contains, in addition to the massless higher spin fields, two complex scalars (of equal mass).
• The mass is directly related to the 't Hooft coupling constant of the dual CFT.
