# On the tree level S matrix of Yang-Mills theory

@article{Roiban2004OnTT, title={On the tree level S matrix of Yang-Mills theory}, author={Radu Roiban and Marcus Spradlin and Anastasia Volovich}, journal={Physical Review D}, year={2004}, pages={026009} }

In this note we further investigate the procedure for computing tree-level amplitudes in Yang-Mills theory from connected instantons in the B-model on P^{3|4}, emphasizing that the problem of calculating Feynman diagrams is recast into the problem of finding solutions to a certain set of algebraic equations. We show that the B-model correctly reproduces all 6-particle amplitudes, including non-MHV amplitudes with three negative and three positive helicity gluons. As a further check, we also…
