Gravity Amplitudes from Double Bonus Relations
Original language description
In this Letter, we derive new expressions for tree-level graviton amplitudes in N 1/4 8 supergravity fromBritto-Cachazo-Feng-Witten (BCFW) recursion relations combined with new types of bonus relations.These bonus relations go beyond the famous 1=z2 behavior under a large BCFW shift and use knowledgeabout certain zeros of graviton amplitudes in collinear kinematics. This extra knowledge can be used in thecontext of global residue theorems by writing the amplitude in a special form using canonical buildingblocks. In the next-to-maximally-helicity-violating case, these building blocks are dressed one-loop leadingsingularities, the same objects that appear in the expansion of Yang-Mills amplitudes, where each termcorresponds to an R invariant. Unlike other approaches, our formula is not an expansion in terms of cyclicobjects and does not manifest color-kinematics duality but rather preserves the permutational symmetry ofits building blocks.We also comment on the possible connection to Grassmannian geometry and give somenontrivial evidence of such structure for graviton amplitudes.
