On-shell representation and further instances of the 2-split behavior of amplitudes
Thales Azevedo, Humberto Gomez, Renann Lipinski Jusinskas
The newly discovered splitting behavior of tree-level scattering amplitudes of particles and strings has been expressed in terms of currents containing one off-shell leg. In this w…
A Novel On-Shell Recursive Relation
Humberto Gomez
We present a novel framework for deriving on-shell recursion relations, with a specific focus on biadjoint and pure Yang-Mills theories. Starting from the double-cover CHY factoriz…
One-loop -point correlators in pure gravity
Humberto Gomez, Renann Lipinski Jusinskas, Cristhiam Lopez-Arcos +1
In this work we propose a simple algebraic recursion for the complete one-loop integrands of -graviton correlators. This formula automatically yields the correct symmetry factor…
New recursions for tree-level correlators in (Anti) de Sitter space
Connor Armstrong, Humberto Gomez, Renann Lipinski Jusinskas +2
We present for the first time classical multiparticle solutions in Anti de Sitter space (AdS) involving scalars, gluons, and gravitons. They are recursively defined through multipa…
One-loop off-shell amplitudes from classical equations of motion
Humberto Gomez, Renann Lipinski Jusinskas, Cristhiam Lopez-Arcos +1
In this letter we present a recursive method for computing one-loop off-shell amplitudes in colored quantum field theories. First, we generalize the perturbiner method by recasting…
Effective Field Theories and Cosmological Scattering Equations
Connor Armstrong, Humberto Gomez, Renann Lipinski Jusinskas +2
We propose worldsheet formulae for wavefunction coefficients of the massive non-linear sigma model (NLSM), scalar Dirac-Born-Infeld (DBI), and special Galileon (sGal) theories in d…
