Abstract

摘要

In this talk, I will introduce two types of recursive relations for tree level multi-trace Einstein-Yang-Mills (EYM) amplitudes. With these relations, one can establish the rules for expanding all tree-level multi-trace EYM amplitudes in terms of pure Yang-Mills ones. I will talk about the BCFW recursion and CHY formula approaches. The consistency of these relations and the corresponding gauge invariance identities (two types of generalized BCJ relations) will also be introduced.
