QUANTUM STRINGS IN AdS5 S5 AND GAUGE{STRING DUALITY

摘要

We review some recent progress in understanding the spectrum of energies/dimensions of strings/operators in AdS5 S5 { planar N=4 super Yang-Mills correspondence. We consider leading strong coupling corrections to the energy of lightest massive string modes in AdS5S5 , which should be dual to members of the Konishi operator multiplet in the SYM theory. This determines the general structure of strong-coupling expansion of the anomalous dimension of the Konishi operator. We use 1-loop results for semiclassical string states to extract information about the leading coecients in this expansion.
