We discuss the universal soft behavior of form factors in the $\mathcal N=4$ 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 $\mathfrak{gl}(4|4)$ integrable spin chain.
Keywords: $\mathcal N=4$ supersymmetric Yang–Mills theory, form factor, integrability, soft theorem.
