Sumario:An update of the search for an invisibly decaying Higgs boson with the data collected in 2000 by the ALEPH experiment at centre-of-mass energies up to 209 GeV is presented and combined with previous results obtained with data collected from 189 GeV upwards. A lower mass limit is set for a Higgs boson with completely invisible decays and with a production cross section equal to that of the standard model.
