The Standard Model Higgs boson search at LEP: combined results
Pedro Teixeira-Dias
TL;DR
The paper reports combined results from LEP experiments in 2000, indicating a 2.9 sigma excess consistent with a Standard Model Higgs boson at 115 GeV/c2, suggesting possible evidence for the particle.
Contribution
First combined analysis of LEP data showing a potential Higgs signal at 115 GeV/c2 with 2.9 sigma significance.
Findings
Evidence of a Higgs boson signal at 115 GeV/c2
2.9 sigma excess over background
Consistent with Standard Model predictions
Abstract
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.
