摘要

In a search for the Standard Model Higgs boson, carried out on 212.5~$\mathrm{pb^{-1}}$ of data collected by the L3 detector at the highest LEP centre-of-mass energies, including 116.5~$\mathrm{pb^{-1}}$ above $\sqrt{s} = 206$~GeV, an excess of candidates for the process $e^+ e^- \rightarrow Z^{*}\rightarrow HZ$ is found for Higgs masses near 114.5~GeV. We present an analysis of our data and the characteristics of our strongest candidates.
