Using a data sample corresponding to about 1 233 000 hadronic Z decays
collected by the ALEPH experiment at LEP, the reaction e+e- --> HZ h
as been used to search for the standard model Higgs boson, in associat
ion with missing energy when Z --> nunuBAR, or with a pair of energet
ic leptons when Z --> e+e- or mu+mu-. No signal was found and, at the
95% confidence level, m(H) exceeds 58.4 GeV/c2.
