| dc.description.abstract | This dissertation describes a search for Z boson pair production decaying into four muon, four electron, and two muon two electron final states with approximately 1 fb^-1 of data at the Fermilab Tevatron Collider at sqrt(s)=1.96 TeV. The small cross section times branching ratio for each channel mandated a thorough study of the acceptance and efficiencies. After optimization, 1.7 +- 0.1 events are expected for Standard Model production with a background of 0.13 +- 0.03 events. One event was found in the two muons two electron channel. A cross section limit of 4.4 pb is determined at a 95% confidence level for Standard Model production. Additionally, one parameter and two parameter 95% C.L. limits are found for the anomalous neutral trilinear gauge couplings ZZZ* and ZZgamma*. The one parameter 95% C.L. coupling limits with a form factor scale of 1.2~TeV are: -0.28 f_40^Z<0.28, -0.31<f_50^Z<0.29, -0.26<f_40^gamma<0.26, and -0.30<f_50^gamma<0.28. | en_US |
