Simplex-like Structures of Maximally Supersymmetric Scattering Amplitudes
Junjie Rao
We elaborate the two-fold simplex-like structures of tree amplitudes in planar maximally supersymmetric Yang-Mills (N=4 SYM), through its connection to a mathematical structure kno…
All-loop Mondrian Diagrammatics and 4-particle Amplituhedron
Yang An, Yi Li, Zhinan Li +1
Based on 1712.09990 which handles the 4-particle amplituhedron at 3-loop, we have found an extremely simple pattern, yet far more non-trivial than one might naturally expect: the a…
4-particle Amplituhedron at 3-loop and its Mondrian Diagrammatic Implication
Junjie Rao
This article provides a direct calculation of the 4-particle amplituhedron at 3-loop order, by introducing a set of practical tricks. After delicately rearranging each piece of thi…
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,…
