Solution to the Ward identities for superamplitudes

Supersymmetry and R-symmetry Ward identities relate on-shell amplitudes in a supersymmetric field theory. We solve these Ward identities for N [superscript K] MHV amplitudes of the maximally supersymmetric =4 and =8 theories. The resulting superamplitude is written in a new, manifestly supersymmetri...
