Multiparticle solutions to Einstein's equations
Humberto Gomez, Renann Lipinski Jusinskas
In this letter we present the first multiparticle solutions to Einstein's field equations in the presence of matter. These solutions are iteratively obtained via the perturbiner me…
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…
Scalar-Graviton Amplitudes
N. E. J. Bjerrum-Bohr, Andrea Cristofoli, Poul H. Damgaard +1
Using the CHY-formalism and its extension to a double cover we provide covariant expressions for tree-level amplitudes with two massive scalar legs and an arbitrary number of gravi…
Scattering Equations and Factorization of Amplitudes II: Effective Field Theories
Humberto Gomez, Andreas Helset
We continue the program of extending the scattering equation framework by Cachazo, He and Yuan to a double-cover prescription. We discuss how to apply the double-cover formalism to…
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…
