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…
CHY-Graphs on a Torus
Carlos Cardona, Humberto Gomez
Recently, we proposed a new approach using a punctured Elliptic curve in the CHY framework in order to compute one-loop scattering amplitudes. In this note, we further develop this…
Cross-ratio Identities and Higher-order Poles of CHY-integrand
Carlos Cardona, Bo Feng, Humberto Gomez +1
The evaluation of generic Cachazo-He-Yuan(CHY)-integrands is a big challenge and efficient computational methods are in demand for practical evaluation. In this paper, we propose a…
Elliptic scattering equations
Carlos Cardona, Humberto Gomez
Recently the CHY approach has been extended to one loop level using elliptic functions and modular forms over a Jacobian variety. Due to the difficulty in manipulating these kind o…
Scattering Equations
Humberto Gomez
The CHY representation of scattering amplitudes is based on integrals over the moduli space of a punctured sphere. We replace the punctured sphere by a double-cover version. The re…
