Limits on Anomalous Trilinear Gauge Couplings in Z gamma Events from p(p)over-bar Collisions at root s=1.96 TeV

Abstract

Using Z candidate events collected by the CDF detector at the Tevatron Collider, we search for potential anomalous (non-standard-model) couplings between the Z boson and the photonZ couplings vanish at tree level and are heavily suppressed at higher orders hence any evidence of couplings indicates new physics. Measurements are performed using data corresponding to an integrated luminosity of 4:9 fb1 in the Z ! decay channel and 5:1 fb1 in the Z ! lþl (l ¼ , e) decay channels.
