In this paper we study the spectrum of bosonic string theory on AdS_3. We study classical solutions of the SL(2,R) WZW model, including solutions for long strings with non-zero winding number. We show that the model has a symmetry relating string configurations with different winding numbers. We then study the Hilbert space of the WZW model, including all states related by the above symmetry. This leads to a precise description of long strings. We prove a no-ghost theorem for all the representations that are involved and discuss the scattering of the long string.

- Logarithmic conformal field theory: beyond an introduction (2013, background): “found in [122–124]. The link with the Wess-Zumino-Witten model on SL 2;R is interesting because it suggests that these theories may be logarithmic for general values of the level. The famous articles [38,125,126] of Maldacena and Ooguri suggest no logarithmic structure for this model, though it coul”
