We investigate low-energy string excitations in AdS 3× S 3× T 4. When the worldsheet is decompactified, the theory has gapless modes whose spectrum at low energies is determined by massless relativistic integrable S matrices of the type introduced by Al. B. Zamolodchikov. The S matrices are non-trivial only for excitations with identical worldsheet chirality, indicating that the low-energy theory is a CFT 2. We construct a Thermodynamic Bethe Ansatz (TBA) for these excitations and show how the massless modes’ wrapping effects may be incorporated into the AdS 3 spectral problem. Using the TBA and its associated Y-system, we determine the central charge of the low-energy CFT 2 to be c= 6 from calculating the vacuum energy for antiperiodic fermions—with the vacuum energy being zero for periodic fermions in agreement with a supersymmetric theory—and find the energies of some excited states.
