Einstein-Yang-Mills from pure Yang-Mills amplitudes
Einstein-Yang-Mills from pure Yang-Mills amplitudes
We present new relations for scattering amplitudes of color ordered gluons and gravitons in Einstein-Yang-Mills theory. Tree-level amplitudes of arbitrary multiplicities and polarizations involving up to three gravitons and up to two color traces are reduced to partial amplitudes of pure Yang-Mills theory. In fact, the double-trace identities apply to …
