CHY representations for gauge theory and gravity amplitudes with up to three massive particles
arXiv:1501.03500 · doi:10.1007/JHEP05(2015)050
Abstract
We show that a wide class of tree-level scattering amplitudes involving scalars, gauge bosons, and gravitons, up to three of which may be massive, can be expressed in terms of a Cachazo-He-Yuan representation as a sum over solutions of the scattering equations. These amplitudes, when expressed in terms of the appropriate kinematic invariants, are independent of the masses and therefore identical to the corresponding massless amplitudes.
