• We propose a new formulation of the complete tree-level S-matrix of N = 8 supergravity. The new formula for n particles in the k R-charge sector is an integral over the Grassmannian G(2,n) and uses the Veronese map into G(k,n). The image of a point in G(2,n) is required to be in the “complement” of a 2|8-plane thus making the SU(8) R-symmetry manifest. The integrand is the ratio of two determinants. The numerator is an analog of Hodges’ recent determinant formula for MHV amplitudes. The… CONTINUE READING
