Abstract

The formulation of gauge theory resulting from all n-point conjugate-maximal-helicity-violating (MHV) amplitudes which provided strong support to the string theory construction was discussed. A technique for computing scattering amplitudes for supersymmetric gauge theory was also proposed. The string theory construction suggested that the amplitudes might receive nonvanishing contributions from disconnected curves connected by the twistor space propagator of the gauge theory fields. The momentum conservation constraint and the remaining constraints were exposed into a more useful form.
