We discuss semiclassical quantization of closed superstrings in AdS5×S. We consider two basic examples: point-like string boosted along large circle of S and folded string rotating in AdS5. In the first case we clarify the general structure of the sigma model perturbation theory for the energy of string states beyond the 1-loop order (related to the plane-wave limit). In the second case we argue that the large spin limit of the expression for the ground-state energy (i.e. for the dimension of… CONTINUE READING
