Superconformal Ward Identities and N=2 Yang-Mills Theory
arXiv:hep-th/9607239 · doi:10.1016/S0550-3213(96)00628-1
Abstract
A reformulation of the superconformal Ward identities that combines all the superconformal currents and the associated parameters in one multiplet is given for theories with rigid N=1 or N=2 supersymmetry. This form of the Ward Identities is applied to spontaneously broken N=2 Yang-Mills theory and used to derive a condition on the low energy effective action. This condition is satisfied by the solution proposed by Seiberg and Witten.
