Universal Interpretation of Hidden Zero and $2$ -Split of Tree-Level Amplitudes Using Feynman Diagrams, Part $I$ : $Tr (I ¨ ^{3})$ , NLSM and YM

Kang Zhou

In this paper, we propose a universal diagrammatic interpretation of hidden zeros and $2$ -splits of tree-level amplitudes. Originally developed for $Tr (I ¨ ^{3})$ amplitudes in o…

Towards New Hidden Zero and $2$ -Split of Loop-Level Feynman Integrands in $Tr (I ¨ ^{3})$ Model

Kang Zhou

We extend the hidden zeros and $2$ -split of tree-level $Tr (I ¨ ^{3})$ amplitudes to loop-level Feynman integrands, apart from some physically irrelevant scaleless integrals. Our…

Generalized $2$ -split for higher-derivative YM and GR amplitudes at tree-level

Liang Zhang, Kang Zhou

We study the generalized $2$ -split of higher-derivative amplitudes, including Yang-Mills (YM) and Gravity (GR) amplitudes with special insertions of higher-derivative vertices, by…

$2$ -split from Feynman diagrams and Expansions

Bo Feng, Liang Zhang, Kang Zhou

In this paper, we investigate the $2$ -split behavior of tree-level amplitudes of bi-adjoint scalar (BAS), Yang-Mills (YM), non-linear sigma model (NLSM), and general relativity (GR…
