Z boson pair-production at LEP

Z boson pair-production at LEP

Events stemming from the pair-production of Z bosons in e+e− collisions are studied using 217.4 pb−1 of data collected with the L3 detector at centre-of-mass energies from 200 GeV up to 209 GeV. The special case of events with b quarks is also investigated. Combining these events with those collecte...

Zusammenfassung:Events stemming from the pair-production of Z bosons in e+e− collisions are studied using 217.4 pb−1 of data collected with the L3 detector at centre-of-mass energies from 200 GeV up to 209 GeV. The special case of events with b quarks is also investigated. Combining these events with those collected at lower centre-of-mass energies, the Standard Model predictions for the production mechanism are verified. In addition, limits are set on anomalous couplings of neutral gauge bosons and on effects of extra space dimensions.
