Soft Graviton Theorem in Arbitrary Dimensions
Published 14 May 2014 in hep-th | (1405.3533v1)
Abstract: In this note we show that the recent conjecture proposed by Cachazo and Strominger holds at tree level in arbitrary dimensions. The proof makes crucial use of the fact that the sub-leading operator is defined using the total angular momentum operator. A key ingredient that makes the proof possible is the CHY formula for graviton amplitudes in arbitrary number of dimensions.
