| 英文摘要 | The pair production of Z bosons is studied using the data collected by the L3 detector at LEP in 1998 in e(+)e(-) collisions at a centre-of-mass energy of 189 GeV. All the visible final states are considered and the cross section of this process is measured to be 0.74(-0.14)(+0.15)(stat.) +/- 0.04(syst)pb. Final states containing b quarks are enhanced by a dedicated selection and their production cross section is found to be 0.18(-0.07)(+0.09)(stat) +/- 0.02(syst) pb. Both results are in agreement with the Standard Model predictions. Limits on anomalous couplings between neutral gauge bosons are derived from these measurements.
