Boundary Contributions of On-shell Recursion Relations With Multiple-line Deformation
Chang Hu, Xiao-Di Li, Yi Li
On-shell recursion relation has been recognized as a powerful tool for calculating tree level amplitudes in quantum field theory, but it doesn't work well when the residue of the d…

Expansion of EYM Amplitudes in Gauge Invariant Vector Space
Bo Feng, Xiao-Di Li, Rijun Huang
Motivated by the problem of expanding single-trace tree-level amplitude of Einstein-Yang-Mills theory to the BCJ basis of Yang-Mills amplitudes, we present an alternative expansion…
