SUSY Ward identities, Superamplitudes, and Counterterms

Ward identities of SUSY and R-symmetry relate n-point amplitudes in supersymmetric theories. We review recent work in which theseWard identities are solved in N = 4 SYM and N = 8 supergravity. The solution, valid at both tree and loop level, expresses any N[superscript K]MHV superamplitude in terms...
