Measurement of the WZ production cross section and limits on anomalous triple gauge couplings at √s = 7 TeV using the ATLAS detector

Michael Aaron Kagan

This dissertation presents a measurement of the W&plusmnZ production cross section and limits on anomalous triple gauge couplings in proton-proton collisions at a center of mass energy of 7 TeV using data produced by LHC collisions and acquired by the ATLAS detector in 2011. The measurement and limits probe the electroweak sector of the Standard Model at high energies and allow for generic tests for new physics that could be present at high energy scales. This analysis is also useful for understanding the ATLAS detector response in the presence of multi-lepton signatures.
