Book excerpt: This Letter describes the current most precise measurement of the WZ production cross section as well as limits on anomalous WWZ couplings at a center-of-mass energy of 1.96 TeV in proton-antiproton collisions. The WZ candidates are reconstructed from decays containing three charged leptons and missing energy from a neutrino, where the charged leptons are either electrons or muons. Using data collected by the CDF II detector (7.1 fb−1 of integrated luminosity), 64 candidate events are observed with the expected background contributing 8 ± 1 events. The measured total cross section?(p{bar p} → WZ) = 3.93{sub -0.53}{sup +0.60}(stat){sub -0.46}{sup +0.59}(syst) pb is in good agreement with the standard model prediction of 3.50 ± 0.21. The same sample is used to set limits on anomalous WWZ couplings.
