New Factorization Relations for Yang Mills Amplitudes
arXiv:1810.05023 · doi:10.1103/PhysRevD.99.025014
Abstract
A double-cover extension of the scattering equation formalism of Cachazo, He and Yuan (CHY) leads us to conjecture covariant factorization formulas of n-particle scattering amplitudes in Yang-Mills theories. Evidence is given that these factorization relations are related to Berends-Giele recursions through repeated use of partial fraction identities involving linearized propagators.
