CHY Loop Integrands from Holomorphic Forms
Humberto Gomez, Sebastian Mizera, Guojun Zhang
Recently, the Cachazo-He-Yuan (CHY) approach for calculating scattering amplitudes has been extended beyond tree level. In this paper, we introduce a way of constructing CHY integr…
Scattering Equations: Real Solutions and Particles on a Line
Freddy Cachazo, Sebastian Mizera, Guojun Zhang
We find -dimensional regions of the space of kinematic invariants, where all the solutions to the scattering equations (the core of the CHY formulation of amplitudes) for…
Inverse of the String Theory KLT Kernel
Sebastian Mizera
The field theory Kawai-Lewellen-Tye (KLT) kernel, which relates scattering amplitudes of gravitons and gluons, turns out to be the inverse of a matrix whose components are bi-adjoi…
Extensions of Theories from Soft Limits
Freddy Cachazo, Peter Cha, Sebastian Mizera
We study a variety of field theories with vanishing single soft limits. In all cases, the structure of the soft limit is controlled by a larger theory, which provides an extension…
