Abstract
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 LÜscher formula based on these twisted S-matrix elements. The result agrees exactly with the perturbative gauge theory computations. © 2010 Elsevier B.V.
