This document presents a measurement of WZ production in 1.02 fb-1 of pp
collision data at CME of 7 TeV collected by the ATLAS experiment at LHC in
2011. The production cross-section is measured to be consistent with the
Standard Model (SM) prediction. Limits on anomalous triple gauge boson
couplings have been derived.Comment: Proceeding for DPF 2011 meetin
