Abstract

We describe a general purpose Mathematica(TM) package for computing superfield operator product expansions (SOPEs) in meromorphic N = 2 superconformal field theory. Given the SOPEs for a set of 'basic' superfields, SOPEs of arbitrarily complicated composites can be computed automatically. Normal ordered products are always reduced to a standard form. It is possible to check the Jacobi identities, and to compute Poisson brackets ('classical SOPEs'). We present two explicit examples: a construction of the 'small' N = 4 superconformal algebra in terms of N= 2 superfields, and a realization of the N = 2 superconformal algebra in terms of chiral and antichiral fermionic superfields.
