Abstract

The operator product expansion in four-dimensional superconformal field theory is discussed. It is demonstrated that the OPE takes a particularly simple form for certain classes of operators. These are chiral operators, principally of interest in theories with N = 1 or N = 2 supersymmetry, and analytic operators, of interest in N = 2 and N = 4. It is argued that the Green's functions of such operators can be determined up to constants.
