Non-renormalization for planar Wess-Zumino model
arXiv:hep-th/0311266 · doi:10.1016/j.physletb.2004.05.050
Abstract
Using a non-perturbative functional method, where the quantum fluctuations are gradually set up,it is shown that the interaction of a N=1 Wess-Zumino model in 2+1 dimensions does not get renormalized. This result is valid in the framework of the gradient expansion and aims at compensating the lack of non-renormalization theorems.
