Correlation functions of conserved currents in calN = 2 superconformal theory

Abstract

Using a manifestly supersymmetric formalism, we determine the general structure of two-and three-point functions of the supercurrent and the flavour current of N = 2 superconformal field theories. We also express them in terms of N = 1 superfields and compare to the generic N = 1 correlation functions. A general discussion of the N = 2 supercurrent superfield and the multiplet of anomalies and their definition as derivatives with respect to the supergravity prepotentials is also included.
