How robust is the result of the Standard Model Higgs boson search at LEP?
M. Kado
TL;DR
This paper discusses a 2000 LEP search for the Standard Model Higgs boson, where an excess of events suggests a potential Higgs at 115 GeV/c2, supported by robustness checks.
Contribution
It provides an analysis of the robustness and consistency of the observed excess, strengthening the potential Higgs signal claim.
Findings
Approximately three sigma excess observed
Consistent with a Higgs boson at 115 GeV/c2
Robustness checks support the signal interpretation
Abstract
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.
