N=6 super Chern-Simons theory S-matrix and all-loop Bethe ansatz equations

We propose the exact S-matrix for the planar limit of the N = 6 super Chern-Simons theory recently proposed by Aharony, Bergman, Jafferis, and Maldacena for the AdS(4)/CFT3 correspondence. Assuming SU(2 vertical bar 2) symmetry, factorizability and certain crossing-unitarity relations, we find the S-matrix including the dressing phase. We use this S-matrix to formulate the asymptotic Bethe ansatz. Our result for the Bethe-Yang equations and corresponding Bethe ansatz equations confirms the all-loop Bethe ansatz equations recently conjectured by Gromov and Vieira.
