Thermodynamic Bethe ansatz for the AdS 5 × S 5 mirror model

Abstract

We use the string hypothesis for the mirror theory to derive the Thermodynamic Bethe Ansatz equations for the AdS 5 × S 5 mirror model. We further demonstrate how these equations can be used to construct the associated Y-system recently discussed in the literature, putting particular emphasis on the assumptions and the range of validity of the corresponding construction. © SISSA 2009.
