Spectral Flow in AdS(3)/CFT(2)

Understand

We study the spectral flowed sectors of the H3 WZW model in the context of the holographic duality between type IIB string theory in AdS(3)x S^3 x T^4 with NSNS flux and the symmetric product orbifold of T^4.

• We construct explicitly the physical vertex operators in the flowed sectors that belong to short representations of the superalgebra, thus completing the bulk-to-boundary dictionary for 1/2 BPS states.
• We perform a partial calculation of the string three-point functions of these operators.
• A complete calculation would require the three-point couplings of non-extremal flowed operators in the H3 WZW model, which are at present unavailable.
