The ZZ production cross section is measured from a data sample corresponding to a total integrated luminosity of 452 pb(-1), collected by the ALEPH experiment at LEP at centre-of-mass energies from 192 to 209 GeV. Individual cross sections, extracted at six centre-of-mass energies, are found to be in agreement with Standard Model calculations. The results are used to set limits on anomalous neutral gauge couplings.

Abstract
The ZZ production cross section is measured from a data sample corresponding to a total integrated luminosity of 452 pb(-1), collected by the ALEPH experiment at LEP at centre-of-mass energies from 192 to 209 GeV. Individual cross sections, extracted at six centre-of-mass energies, are found to be in agreement with Standard Model calculations. The results are used to set limits on anomalous neutral gauge couplings.File in questo prodotto:
