  • Supersymmetry and R-symmetry Ward identities relate on-shell amplitudes in a supersymmetric field theory. We solve these Ward identities for NKMHV amplitudes of the maximally supersymmetric $ \mathcal{N} = 4 $ and $ \mathcal{N} = 8 $ theories. The resulting superamplitude is written in a new, manifestly supersymmetric and R-invariant form: it is expressed as a sum of very simple SUSY and $ {\text{SU}}{\left( \mathcal{N} \right)_R} $-invariant Grassmann polynomials, each multiplied by a “basis… CONTINUE READING
