Description

The authors present a study of {mu}{mu}{mu}{mu}, eeee, and {mu}{mu}ee events using 1 fb{sup -1} of data collected with the D0 detector at the Fermilab Tevatron p{bar p} Collider at {radical}s = 1.96 TeV. Requiring the lepton pair masses to be greater than 30 GeV, they observe one event, consistent with the expected background of 0.13 {+-} 0.03 events and with the predicted standard model ZZ and Z{gamma}* production of 1.71 {+-} 0.15 events. They set an upper limit on the ZZ and Z{gamma}* cross section of 4.4 pb at the 95% C.L. They also derive limits on anomalous neutral ... continued below

Description

The authors present a study of {mu}{mu}{mu}{mu}, eeee, and {mu}{mu}ee events using 1 fb{sup -1} of data collected with the D0 detector at the Fermilab Tevatron p{bar p} Collider at {radical}s = 1.96 TeV.

They set an upper limit on the ZZ and Z{gamma}* cross section of 4.4 pb at the 95% C.L. They also derive limits on anomalous neutral trilinear ZZZ and ZZ{gamma}* gauge couplings. The one-parameter 95% C.L. coupling limits with a form factor scale {Lambda} = 1.2 TeV are -0.28 < f{sub 40}{sup Z} < 0.28, -0.31 < f{sub 50}{sup Z} < 0.29, -0.26 < f{sub 40}{sup y} < 0.26, and -0.30 < f{sub 50}{sup y} < 0.28.
