Twistor String Techniques for Scattering Amplitudes - Einstein-Yang-Mills and chiral factorization
Abstract
This talk is about a 4d "(ambi-)twistor string" formula for sEYM tree-level scattering amplitudes and is work in progress. The formula sheds some new light on the translation between CHY formulae and (ambi-)twistor formulae in general, potentially even at loop level.
