Resumo
We study the processes pp̄→WZ→ ±ν +- and pp̄→ZZ→ + -νν̄, where =e or μ. Using 8.6fb -1 of integrated luminosity collected by the D0 experiment at the Fermilab Tevatron collider, we measure the WZ production cross section to be 4.50-0.66+0.63pb which is consistent with, but slightly larger than, the prediction of the standard model. The ZZ cross section is measured to be 1.64±0.46pb, in agreement with a prediction of the standard model. Combination with an earlier analysis of the ZZ→ +-+- channel yields a ZZ cross section of 1.44-0.34+0.35pb. © 2012 American Physical Society.
