A Proof of the Explicit Minimal-basis Expansion of Tree Amplitudes in Gauge Field Theory
Yi-Xin Chen, Yi-Jian Du, Bo Feng
In last couple years, an important relation (BCJ relation) between color-ordered tree-level scattering amplitudes of gauge theory has inspired many studies. This relation implies t…

On tree amplitudes with gluons coupled to gravitons
Yi-Xin Chen, Yi-Jian Du, Bo Feng
In this paper, we study the tree amplitudes with gluons coupled to gravitons. We first study the relations among the mixed amplitudes. With BCFW on-shell recursion relation, we wil…
