Abstract

We discuss the universal soft behavior of form factors in the N=4 maximally supersymmetric Yang–Mills theory in the limit where the momentum of one of the particles tends to zero. We present details of how the tree-level form factors of this theory are related to eigenfunctions of a gl(4|4) integrable spin chain.
