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 = 2 superconformal field theories. We also express them in terms of = 1 superfields and compare to the generic = 1 correlation functions. A general discussion of the = 2 supercurrent superfield and the multiplet of anomalies and their definition as derivatives with respect to the supergravity prepotentials is also included.
