A search for the Standard Model Higgs boson is carried out on 176.4 pb(-1)
of data collected by the L3 detector at a center-of-mass energy of 189 GeV.
The data are consistent with the expectations of Standard Model processes
and no evidence of a Higgs signal is observed. Combining the results of thi
s search with those at lower center-of-mass energies, a lower limit on the
mass of the Standard Model Higgs boson of 95.3 GeV is set at the 95% confid
ence level. (C) 1999 Elsevier Science B.V, All rights reserved.
