arXiv:1407.5936 · doi:10.1007/JHEP10(2014)148

Abstract

The CHY formula which describes an -point tree level scattering amplitude for scalars, gluons or gravitons in arbitrary dimension [22], is used to prove the sub-sub-leading soft- graviton theorem recently proposed by Cachazo and Strominger [13].
