Search for the standard model Higgs boson

Abstract
The Higgs boson, which plays a central role in electroweak symmetry
breaking as postulated by the standard model, has not yet been
observed experimentally. Final search results from the four LEP
experiments indicate that the mass of the Higgs boson must be greater
than 114 times the proton mass. Experiments at the Tevatron,
currently the world's highest-energy particle accelerator, seek to
constrain further the standard model Higgs boson mass through both
direct searches and precision electroweak measurements. The direct
search for Higgs boson production and decay requires detailed
knowledge of the data sample composition as well as good dijet
invariant mass resolution. New results from the search for the Higgs
boson using data from the Collider Detector at Fermilab highlight the
challenges of Higgs hunting at present and future hadron colliders.
