# Tree-level split helicity amplitudes in ambitwistor space

@article{Chen2009TreelevelSH, title={Tree-level split helicity amplitudes in ambitwistor space}, author={Bin Chen and Jun-bao Wu}, journal={Physical Review D}, year={2009}, volume={80}, pages={125031} }

We study all tree-level split helicity gluon amplitudes by using the recently proposed Britto-Cachazo-Feng-Witten recursion relation and Hodges diagrams in ambitwistor space. We pick out the contributing diagrams and find that all of them can be divided into triangles in a suitable way. We give the explicit expressions for all of these amplitudes. As an example, we reproduce the six-gluon split next-to-maximally-helicity-violating amplitudes in momentum space.
