A graphic approach to gauge invariance induced identity
Linghui Hou, Yi-Jian Du
All tree-level amplitudes in Einstein-Yang-Mills (EYM) theory and gravity (GR) can be expanded in terms of color ordered Yang-Mills (YM) ones whose coefficients are polynomial func…

Gauge invariance induced relations and the equivalence between distinct approaches to NLSM amplitudes
Yi-Jian Du, Yong Zhang
In this paper, we derive generalized Bern-Carrasco-Johansson relations for color-ordered Yang-Mills amplitudes by imposing gauge invariance conditions and dimensional reduction app…
