# Scattering amplitudes and BCFW recursion in twistor space

@article{Mason2009ScatteringAA, title={Scattering amplitudes and BCFW recursion in twistor space}, author={Lionel Mason and David Skinner}, journal={Journal of High Energy Physics}, year={2009}, volume={2010}, pages={1-66} }

Twistor ideas have led to a number of recent advances in our understanding of scattering amplitudes. Much of this work has been indirect, determining the twistor space support of scattering amplitudes by examining the amplitudes in momentum space. In this paper, we construct the actual twistor scattering amplitudes themselves. We show that the recursion relations of Britto, Cachazo, Feng and Witten have a natural twistor formulation that, together with the three-point seed amplitudes, allows us…
