Tests of neutral gauge boson self-couplings with e$^{+}$e$^{-}$ --> gamma.Z

Shows how the reaction e^{+}e^{-} to gamma Z provides a test of the ZZ gamma and gamma /sub V/Z gamma couplings. The authors calculate the third-order QED contribution (triangular diagrams). They show how anomalous terms (for example if the Z is a bound state) would reflect in this reaction and more explicitly in the photon spectrum of e/sup + /e^{-} to gamma +lepton pairs.
