One-loop Parke-Taylor factors for quadratic propagators from massless scattering equations 

Gomez, Humberto; Lopez-Arcos, Cristhiam; Talavera, Pedro (Springer Verlag, 2017-10-01)
In this paper we reconsider the Cachazo-He-Yuan construction (CHY) of the so called scattering amplitudes at one-loop, in order to obtain quadratic propagators. In theories with colour ordering the key ingredient is the ...

Non-planar one-loop Parke-Taylor factors in the CHY approach for quadratic propagators 

Ahmadiniaz, Naser; Gomez, Humberto; Lopez-Arcos, Cristhiam (Springer Verlag, 2018-05-01)
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 propagators. By doing this, we were able to identify ...
