Description

We propose that certain twists of the su(2|2)S-matrix elements describe the β-deformation of N=4 supersymmetric Yang-Mills theory. We compute the perturbative four-loop anomalous dimension of the Konishi operator of the deformed gauge theory from the Luescher formula based on these twisted S-matrix elements. The result agrees exactly with the perturbative gauge theory computations.
