Abstract

The ZZ production cross section is measured from a data sample correspondingto a total integrated luminosity of 452 pb−1, collected by the ALEPH experiment at LEPat centre-of-mass energies from 192 to 209 GeV. Individual cross sections, extracted at sixcentre-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.
