Title: WZ Production at ATLAS


Studying diboson final states at the Large Hadron Collider allows direct access to some predictions of electroweak physics which have not yet been well measured, and there is room for discovering physics beyond the standard model. I will present studies of WZ production with the ATLAS detector, focusing on the WZ cross section measurement at 7 TeV and limits on anomalous triple gauge couplings. I will conclude with a discussion on the proposed upgrade of the Muon Spectrometer in ATLAS, and show how the data and simulation suggest that we need new precision chambers at small angles for higher instantaneous luminosities.
