摘要：

Search for the Higgs boson is one of the most important topic of the LEP2 program and a great effort has been performed in that field by the four LEP experiments. The collaborations ALEPH, DELPHI, L3 and OPAL, have collected 2465 pb(-1) of e(+)e(-) collision data at energies between 189 GeV and the highest energy of 209 GeV. In the framework of the Standard Model, a lower bound of 114.1 GeV/c(2) has been obtained at the 95% confidence level for the mass of the Higgs boson while the likelihood analysis shows a preference for a Higgs boson with a mass of 115.6 GeV/c(2). Extensions of the Standard Model, including Super symmetry or not, have been investigated by each LEP collaborations.
