    How robust is the result of the Standard Model Higgs boson search at LEP?

    Get PDF
    An excess of signal-like events above the expected background, corresponding to approximately three standard deviations, was observed in the search for the Standard Model Higgs boson at LEP in 2000. This excess is consistent with the existence of a Higgs boson with mass 115GeV/c2. Relevant consistency and robustness checks, which further support the signal interpretation, are presented.Comment: 2 pages, 2 figures, XXXVIth Rencontres de Moriond, France, 200

    Search for an invisibly decaying Higgs boson at LEP at centre-of-mass energies up to 209 GeV

    Get PDF
    An update of the search for an invisibly decaying Higgs boson with the data collected in 2000 by the ALEPH experiment at centre-of-mass energies up to 209 GeV is presented and combined with previous results obtained with data collected from 189 GeV upwards. A lower mass limit is set for a Higgs boson with completely invisible decays and with a production cross section equal to that of the standard model
