Derivation of Feynman Rules for Higher Order Poles Using Cross-ratio Identities in CHY Construction
Kang Zhou, Junjie Rao, Bo Feng
In order to generalize the integration rules to general CHY integrands which include higher order poles, algorithms are proposed in two directions. One is to conjecture new rules,…

Analytic expressions of amplitudes by the cross-ratio identity method
Kang Zhou
In order to obtain the analytic expression of an amplitude from a generic CHY-integrand, a new algorithm based on the so-called cross-ratio identities has been proposed recently. I…
