Abstract

The study of the worldsheet S-matrix for AdS_5×S^5 strings was a key step in the complete determination of the non-pertubrative planar spectrum of anomalous dimensions for N=4 super-Yang-Mills. To go beyond the spectral problem it is important to consider higher-point worldsheet correlation functions and, as is standard in many integrable models, one approach is the study of form factors. We will discuss a set of consistency conditions appropriate to form factors in the light-cone gauge fixed AdS_5×S^5 string theory. We further discuss the  form factors in the weakly coupled dual description, verifying that the relevant conditions naturally hold for the one-loop Heisenberg spin-chain.
