Color-kinematics duality from the Bern-Kosower formalism
Naser Ahmadiniaz, Filippo Maria Balli, Cristhiam Lopez-Arcos +2
Berends-Giele currents are fundamental building blocks for on-shell amplitudes in non-abelian gauge theory. We present a novel procedure to construct them using the Bern-Kosower fo…
One-Loop Yang-Mills Integrands from Scattering Equations
Johannes Agerskov, N. E. J. Bjerrum-Bohr, Humberto Gomez +1
We investigate in the context of the scattering equations, how one-loop linear propagator integrands in gauge theories can be linked to integrands with quadratic propagators using…
-algebras and the perturbiner expansion
Cristhiam Lopez-Arcos, Alexander Quintero Vélez
Certain classical field theories admit a formal multi-particle solution, known as the perturbiner expansion, that serves as a generating function for all the tree-level scattering…
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…
One-loop Parke-Taylor factors for quadratic propagators from massless scattering equations
Humberto Gomez, Cristhiam Lopez-Arcos, Pedro Talavera
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 co…
