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…
