Generalized -split for higher-derivative YM and GR amplitudes at tree-level
Liang Zhang, Kang Zhou
We study the generalized -split of higher-derivative amplitudes, including Yang-Mills (YM) and Gravity (GR) amplitudes with special insertions of higher-derivative vertices, by…
-split from Feynman diagrams and Expansions
Bo Feng, Liang Zhang, Kang Zhou
In this paper, we investigate the -split behavior of tree-level amplitudes of bi-adjoint scalar (BAS), Yang-Mills (YM), non-linear sigma model (NLSM), and general relativity (GR…
Hidden Zeros and -split via BCFW Recursion Relation
Bo Feng, Liang Zhang, Kang Zhou
In this paper, we provide another angle to understand recent discoveries, i.e., the hidden zeros and corresponding 2-split behavior using the BCFW recursion relation. For the hidde…
The canonical differential equations of the one-loop-like integrals
Jiaqi Chen, Bo Feng, Liang Zhang
Recently, a new approach for high loop integrals has been proposed in \cite{Huang:2024nij}, where the whole parameter integration has been divided into two parts: a one-loop-like i…
