Abstract
Recently, by using the known structure of one-loop scattering amplitudes for gluons in Yang-Mills theory, a recursion relation for tree-level scattering amplitudes has been deduced. Here, we give a short and direct proof of this recursion relation based on properties of tree-level amplitudes only.Year: 2005 PMID: 15904356 DOI: 10.1103/PhysRevLett.94.181602
