Results from the direct search for the Standard Model Higgs boson at LEP

The direct search for the Standard Model Higgs boson at LEP, using 2.5 fb−1 of e+e− collision data collected and analyzed by the four LEP collaborations, ALEPH, DELPHI, L3 and OPAL, at center-of-mass energies between 189 and 209 GeV, is pre- sented. The combination of their results by the LEP Higgs...

Sumario:The direct search for the Standard Model Higgs boson at LEP, using 2.5 fb−1 of e+e− collision data collected and analyzed by the four LEP collaborations, ALEPH, DELPHI, L3 and OPAL, at center-of-mass energies between 189 and 209 GeV, is pre- sented. The combination of their results by the LEP Higgs Working Group sets a lower bound for the SM Higgs boson mass of 114.1 GeV/c2 at the 95% confidence level. The excess observed in the higher mass zone, with a significance at the 2 σ level, is described.
