This article 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 for the Collider Detector at Fermilab (CDF). 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), 63 candidate events are observed with the
expected background contributing 8±1 events. The measured total cross
section σ(pp̅ →WZ)=3.93-0.53+0.60(stat)-0.46+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.
