Search for the Standard Model Higgs boson in e$^+$e$^-$ interactions at $\root{s}$ = 189 GeV
L3 Collaboration
TL;DR
This paper reports a search for the Standard Model Higgs boson at 189 GeV using L3 detector data, finding no evidence and setting a lower mass limit of 95.3 GeV at 95% confidence.
Contribution
First search for the Standard Model Higgs boson at 189 GeV, establishing a new lower mass limit based on collider data.
Findings
No Higgs signal observed at 189 GeV
Lower mass limit of 95.3 GeV set at 95% confidence
Results combined with lower energy data for improved limits
Abstract
A search for the Standard Model Higgs boson is carried out on 176.4pb of data collected by the L3 detector at a center-of-mass energy of 189 GeV. The data are consistent with the expectations of Standard Model processes and no evidence of a Higgs signal is observed. Combining the results of this search with those at lower center-of-mass energies, a lower limit on the mass of the Standard Model Higgs boson of 95.3 GeV is set at the 95% confidence level.
