The study of the world-sheet S-matrix for AdS_5 x S^5 strings was a key step
in the complete determination of the spectrum of anomalous dimensions for planar
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 the all-order
functional equations that these objects must obey, their perturbative computation
and their connection to four-dimensional gauge theory three-point functions.
