WZ Production and Triple Gauge Couplings in ATLAS

The measurement of the $WZ$ diboson production cross section in 7 and 8 TeV proton proton interactions is reported from the ATLAS experiment. The measurement is derived from events in which bosons decay leptonically with electrons, muons, and missing energy in the final state. The data are used to test the electroweak sector of the Standard Model and search for evidence for new phenomena. The cross section results are first obtained in phase space regions defined by the decay kinematics and then extrapolated to the full phase space. Differential and total cross sections for WZ production are compared to NLO predictions of the standard model and used to place constraints on anomalous triple gauge boson couplings.
