摘要：

We propose that certain twists of the su(2 vertical bar 2) S-matrix elements describe the beta-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 Luscher formula based on these twisted S-matrix elements. The result agrees exactly with the perturbative gauge theory computations. (C) 2010 Elsevier B.V. All rights reserved.
