PROBING THE WEAK-BOSON SECTOR IN Z-GAMMA PRODUCTION AT HADRON COLLIDERS

A detailed analysis of Zgamma production at hadron colliders is presen ted for general ZZgamma and Zgammagamma couplings. Deviations from the standard model gauge theory structure can be parametrized in terms of four ZZgamma and four Zgammagamma form factors. The high-energy behav ior of these form factors is severely restricted by unitarity. Prospec ts for testing the self-interactions of Z bosons and photons at the Fe rmilab Tevatron, the CERN Large Hadron Collider and the Superconductin g Super Collider are explored. Sensitivity limits for anomalous ZZgamm a and Zgammagamma couplings are derived and compared to bounds from lo w-energy data and e+e- collider experiments.
