# Scattering amplitudes for eight gauge fields

@article{Hodges2006ScatteringAF, title={Scattering amplitudes for eight gauge fields}, author={Andrew P. Hodges}, journal={arXiv: High Energy Physics - Theory}, year={2006} }

We study the scattering of eight gauge fields, and give all the tree-level amplitudes in the helicity-conserved sector. New symmetries are noted, suggesting that significant further simplification can be achieved.
