On the scattering over the GKP vacuum    [PDF]

Davide Fioravanti, Simone Piscaglia, Marco Rossi

By converting the Asymptotic Bethe Ansatz of ${\cal N}=4$ SYM into non-linear integral equations, we find 2D scattering amplitudes of excitations on top of the GKP vacuum. We prove that this is a suitable and powerful set-up for the understanding and computation of the whole S-matrix.
