Holomorphy argument for superpotential non-renormalization
= Holomorphy argument for superpotential non-renormalization
A holomorphy argument treats couplings as chiral <spurions> and constrains the <Wilsonian effective action> <superpotential> to be a <holomorphic function> with the required ordinary charges and <R-charges>. Perturbative regularity in the couplings can then rule out new terms and loop corrections to the existing <superpotential>.
