Tree amplitudes and two-loop counterterms in DÄ11 supergravity

Abstract

We compute the tree level 4-particle bosonic scattering amplitudes in D511 supergravity. By construction, they are part of a linearized supersymmetry, coordinate, and 3-form gauge invariant. While this on-shell invariant is nonlocal, suitable SUSY-preserving differentiations turn it into a local one with correct dimension to provide a natural lowest ~two… (More)
