Description
Within the framework of the AdS_5 /CFT_4 correspondence,
the GKP string living on a AdS_5 ⊗ S^5 background finds a counterpart in
the antiferromagnetic vacuum state for the spin chain, fruitfully employed to
investigate the dual N = 4 SYM superconformal gauge theory. Integrability
underlying such a model allows us to analyse the excitations over the vacuum
considered, by computing their scattering matrices and dispersion relations.
