abstract

A proof is given of the formula, recently proposed by Cachazo, He and Yuan (CHY) for gluon tree amplitudes in pure Yang-Mills theory in arbitrary dimension. The approach is to first establish the corresponding result for massless $\phi^3$ theory using the BCFW recurrence relation and then to extend this to the gauge theory case. Additionally, it is shown that the scattering equations introduced by CHY can be generalized to massive particles, enabling the description of tree amplitudes for massive $\phi^3$ theory.

  1. Scaffolding Residues in Yang-Mills-Scalar \`a la CHY

    hep-th 2024-11 conditional novelty 6.0 of 10

    A CHY-level derivation showing that the scaffolding residue of 2n-scalar Yang-Mills-Scalar amplitudes reproduces n-gluon amplitudes, with the pfaffian of A turning into the pfaffian of Psi.
