摘要：
We construct a convergent cluster expansion for the two-dimensional N = 2 Wess-Zumino model, in a region of parameter space where there are multiple phases. As a result of this expansion, we are able to construct the infinite volume field theory and demonstrate exponential decay of correlations. We are also able to investigate the different phases of the model, develop the phase diagram, and show that the free energy of each phase vanishes.
