-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…

Tensor Reduction of Sunset by Generating Function
Xinhe Chen, Bo Feng, Liang Zhang
Recently, the generating function has been proposed as an alternative reduction method. This method has been tested at the one-loop level, including the tensor reduction and propag…

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…
