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

A detailed analysis of Zgamma production at hadron colliders is presented 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 behavior of these form factors is severely restricted by unitarity. Prospects for testing the self-interactions of Z bosons and photons at the Fermilab Tevatron, the CERN Large Hadron Collider and the Superconducting Super Collider are explored. Sensitivity limits for anomalous ZZgamma and Zgammagamma couplings are derived and compared to bounds from low-energy data and e+e- collider experiments.
