Perturbative Gauge Theory as a String Theory in Twistor Space
Abstract
Perturbative scattering amplitudes in YangMills theory have many unexpected properties, such as holomorphy of the maximally helicity violating amplitudes. To interpret these results, we Fourier transform the scattering amplitudes from momentum space to twistor space, and argue that the transformed amplitudes are supported on certain holomorphic curves. This in turn is apparently a consequence of an equivalence between the perturbative expansion of = 4 super YangMills theory and the Dinstanton expansion of a certain string theory, namely the topological B model whose target space is the CalabiYau supermanifold
