The ALEPH search for the Standard Model Higgs boson in the year 2000 revealed an excess of signal-like events, consistent with a signal hypothesis mh=115 GeV/c2. Here we present the first results after the analysis of all of the data collected during the year 2000, at collision energies up to 209 GeV, and which were published in November 2000.
During the run in the year 2000, with data collected at collision energies up to 209 GeV, the LEP experiments have possibly unearthed the first evidence of a Higgs boson signal at mh=115 GeV/c2. The preliminary combined results prepared immediately after the end of the data-taking, in November 2000, are presented here. Overall, a 2.9 sigma excess over the background is found, consistent with a Standard Model Higgs boson signal with mh=115.0 GeV/c2.
