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…

Minimal Basis in Four Dimensions and Scalar Blocks
Freddy Cachazo, Guojun Zhang
We find a construction that expresses any tree-level -particle color-ordered partial amplitude in gauge theory as a linear combination of a basis of dimension…
