Abstract: (Elsevier)
We compute exactly a class of correlation functions for the 2-d N = 2 Wess-Zumino models with superpotential φ′ and generic Kähler potential. From these functions we extract the central charge, dimensions and OPE coefficients for the corresponding critical theories. These numbers coincide with those of the N = 2 minimal series. This is particularly remarkable for the OPE coefficients which are given by transcendental functions. The WZ models can be reconstructed as stochastic processes. From the N = 2 minimal models we get an IR asymptotical solution to the corresponding stochastic equations. This solution becomes exact in the strong-coupling limit. This shows that these Wess-Zumino models go into the N = 2 minimal series in the critical limit. The results of other non-perturbative methods are outlined.- field theory: conformal
