Abstract: (Elsevier)

The classical amplitude for scattering of two positive helicity and n −2 negative helicity (or the other way) gauge bosons is shown to be generated by a Wess-Zumino-Witten (WZW) model for N =4 supersymmetric gauge theory; i.e. the current algebra of the WZW model (with central charge k =1) gives a Kac-Moody algebra as the symmetry behind these amplitudes.
