Note Aleph authors list : /afs/cern.ch/user/a/alephsec/public/authlist/mickyb.ps IMPORTANT: please let the CERN EP referee know that, since the journal referees asked to add one word ("gauge") to the title, for consistency I have changed it also into the CERN EP preprint, the final title is "Measurement of Z-pair production in e+e- collisions and constraints on anomalous neutral *gauge* couplings" Again, for consistency, I replaced a slightly modified figure (fig. 4, that has now asymmetric errors, hardly visible) and the uncertainties are now split in stat+syst in Eqns 3, 4. There are also a few very minor english corrections in the text. R. Tenchini, 11.3.2009

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.
