摘要：

We have searched for the neutral Higgs boson produced in the decays of the Z0 through the process Z0 --> H0l+ l- in the mass range M(H0) < 2 GeV. From the analysis of a data sample corresponding to about 70 000 Z0 --> hadrons we exclude a minimal standard model Higgs boson in the mass range O < M(HO) < 2 GeV at the 99% confidence level independent of the Higgs decay channels.
