摘要：

Four-point correlation functions of hypermultiplet bilinear composites are analysed in N = 2 superconformal field theory using the superconformal Ward identities and the analyticity properties of the composite operator superfields. It is shown that the complete amplitude is determined by a single arbitrary function of the two conformal cross-ratios of the spacetime variables. (C) 2000 Elsevier Science B.V. All rights reserved.
