Search for the Standard Model Higgs boson in e+e- collisions at root(s) up to 202GeV

TL;DR

This paper reports a search for the Standard Model Higgs boson using data from e+e- collisions at energies up to 202 GeV, finding no evidence and setting a lower mass limit of 107.0 GeV.

Contribution

First search for the Standard Model Higgs boson in e+e- collisions at energies up to 202 GeV with a new lower mass limit established.

Findings

No Higgs signal observed in the data.

Lower mass limit of 107.0 GeV at 95% confidence level.

Data consistent with Standard Model background expectations.

Abstract

The Standard Model Higgs boson is searched for in 233.2 pb-1 of data collected by the L3 detector at centre of mass energies from 192 GeV to 202 GeV. These data are consistent with the expectations of Standard Model processes and no evidence of a Higgs signal is observed. A lower limit on the mass of the Standard Model Higgs boson of 107.0 GeV is set at the 95% confidence level.
