摘要：
We discuss planar scattering amplitudes on the Coulomb branch of N = 4 super Yang-Mills. The vacuum expectation values on the Coulomb branch can be used to regulate infrared divergences. We argue that this has a number of conceptual as well as practical advantages over dimensional regularisation.
