N = 2 superconformal models as topological field theories
Abstract
This paper presents simple observations on the topological nature of {ital N} = 2 superconformal field theories. The authors point out that under a suitable redefinition of the energy-momentum tensor the central charge of {ital N} = 2 theory vanishes and the theory is transformed into a topological quantum field theory. BRST invariant observables are given by chiral primary fields. The authors also discuss the relevant perturbations of {ital N} = 2 and SU(2) coset models.
