Spinor Exchange in $AdS_{d+1}$

We study the Witten diagram with general spinor field exchange on the (d+1)-dimensional Euclidean Anti-de Sitter Space, which is necessary to calculate four-point correlation functions with spinor fields when we make use of the AdS/CFT correspondence, especially, in supersymmetric cases. We show that the amplitude can be expressed by that with scalar field exchange, which have been previously calculated, and we explicitly give our result of the calculation. We discuss the short distance expansion of the amplitude with the interpretation as the operator product expansion of the conformal field theory, according to the AdS/CFT correspondence
