Amplitude Relations in Non-linear Sigma Model
Gang Chen, Yi-Jian Du
In this paper, we investigate tree-level scattering amplitude relations in non-linear sigma model. We use Cayley parametrization. As was shown in the recent works [23,24] bo…

Boundary Behaviors for General Off-shell Amplitudes in Yang-Mills Theory
Yun Zhang, Gang Chen
In this article, we analyze the boundary behaviors of pure Yang-Mills amplitudes under adjacent and non adjacent BCFW shifts in Feynman gauge. We introduce reduced vertexes for Yan…
