The boundary S-matrix and the AdS to CFT dictionary

arXiv:hep-th/9903048 · doi:10.1103/PhysRevLett.83.2707

Abstract

An S-matrix analog is defined for anti-de Sitter space by constructing ``in'' and ``out'' states that asymptote to the timelike boundary. A derivation parallel to that of the LSZ formula shows that this ``boundary S-matrix'' is given directly by correlation functions in the boundary conformal theory. This provides a key entry in the AdS to CFT dictionary.
