During 1997 the ALEPH experiment at LEP gathered 57 pb(-1) of data at centr
e-of-mass energies near 183 GeV. These data are used to look for possible s
ignals from the production of the Standard Model Higgs boson in the reactio
n e(+)e(-) --> HZ. No evidence of a signal is found in the data; seven even
ts are selected, in agreement with the expectation of 7.2 events from backg
round processes. This observation results in an improved lower limit on the
mass of the Higgs boson: m(H) greater-than 87.9 GeV/c(2) at 95% confidence
level. (C) 1999 Elsevier Science B.V. All rights reserved.
