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 superf
ields. It is shown that the complete amplitude is determined by a single ar
bitrary function of the two conformal cross-ratios of the spacetime variabl
