Description

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. We begin by reviewing the original D=4 BCFW approach and its superamplitude genralization. Then we show that 10D spinor helicity formalism by Caron-Huot and O'Connell can be understood as spinor moving frame approach to supersymmetric particles extended to the description of amplitudes. This allowed us to develop the spinor helicity formalism for 11D supergravity and also to find a new superfield representation for 10D SYM and 11D SUGRA superamplitudes, and to obtain the generalizations of the BCFW recurrent relations for these superamplitudes. This talk is based on arXiv:1605.00036[hep-th] and a paper in preparation.
