Abstract
Fusion rules, structure constants and four-point functions for all the fields of N = 2 superconformal minimal models (c ≤ 3) are derived. It is shown that the additional Zp+2 symmetries of these models are generated by specific N = 2 superfields which close the N = 2 superparafermionic algebra. General results are applied to the four- and three-generation Gepner tensor product models and the allowed Yukawa couplings are found. © 1989.| File | Dimensione | Formato | |
