BCFW-type recurrent relations for tree amplitudes of D=11 supergravity
arXiv:1605.00036 · doi:10.1103/PhysRevLett.118.031601
Abstract
We propose the on-shell superfield description for tree amplitudes of D=11 supergravity and the BCFW (Britto-Cachazo-Feng-Witten)-type recurrent relations for these superamplitudes.
