摘要：

In a search for the Standard Model Higgs boson, carried out on 212.5 pb(-1) of data collected by the L3 detector at the highest LEP centre-of-mass energies, including 116.5 pb(-1) above roots = 206 GeV, an excess of candidates for the process e(+)e(-) --> Z* --> HZ is found for Higgs masses near 114.5 GeV. We present an analysis of our data and the characteristics of our strongest candidates. (C) 2000 Elsevier Science B.V. All rights reserved.
