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.

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.
