Query: Structure constants of operators on the Wilson loop from integrability   We study structure constants of local operators inserted on the Wilson loop
in ${\cal N}=4$ super Yang-Mills theory. We compute the structure constants in
the SU(2) sector at tree level using the correspondence between operators on
the Wilson loop and the open spin chain. The results are interpreted as the
summation over all possible ways of changing the signs of magnon momenta in the
hexagon form factors. This is consistent with a holographic description of the
correlator as the cubic open string vertex, which consists of one hexagonal
patch and three boundaries. We then conjecture that a similar expression should
hold also at finite coupling.
