New Factorization Relations for Non-Linear Sigma Model Amplitudes
N. E. J. Bjerrum-Bohr, Humberto Gomez, Andreas Helset
We obtain novel factorization identities for non-linear sigma model amplitudes using a new integrand in the CHY double-cover prescription. We find that it is possible write very co…
Scattering Equations and a new Factorization for Amplitudes I: Gauge Theories
Humberto Gomez
In this work we show how a double-cover (DC) extension of the Cachazo, He and Yuan formalism (CHY) can be used to provide a new realization for the factorization of the amplitudes…
New Factorization Relations for Yang Mills Amplitudes
N. E. J. Bjerrum-Bohr, Poul H. Damgaard, Humberto Gomez
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 amplitu…
Non-planar one-loop Parke-Taylor factors in the CHY approach for quadratic propagators
Naser Ahmadiniaz, Humberto Gomez, Cristhiam Lopez-Arcos
In this work we have studied the Kleiss-Kuijf relations for the recently introduced Parke-Taylor factors at one-loop in the CHY approach, that reproduce quadratic Feynman propagato…
