Query: Quantum mechanics of null polygonal Wilson loops   Scattering amplitudes in maximally supersymmetric gauge theory are dual to
super-Wilson loops on null polygonal contours. The operator product expansion
for the latter revealed that their dynamics is governed by the evolution of
multiparticle GKP excitations. They were shown to emerge from the spectral
problem of an underlying open spin chain. In this work we solve this model with
the help of the Baxter Q-operator and Sklyanin's Separation of Variables
methods. We provide an explicit construction for eigenfunctions and eigenvalues
of GKP excitations. We demonstrate how the former define the so-called
multiparticle hexagon transitions in super-Wison loops and prove their
factorized form suggested earlier.
