One of the most active large research projects today is the search
for an extremely small but energetic particle that is thought to be the
key to understanding how mass appeared shortly after the Big Bang. The
Higgs boson is a hypothetical elementary particle that has not been
observed but, if found, would dramatically advance the 70-year
development of a model of elementary particle interaction. Its existence
was predicted along with other particles by the so-called Standard
Model. The Standard Model describes how leptons, quarks, gauge bosons,
and the Higgs particle fit together and explains how the Higgs mechanism
takes place, which in turn explains why elementary particles exhibit
mass. The discovery of the Higgs boson would finally validate the
Standard Model, since it’s the only elementary particle predicted by it
that hasn’t yet been observed.
Experiments to find the Higgs boson are currently being performed using the Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN) in Switzerland, . The LHC is expected to be able to answer the question of whether or not the Higgs boson actually exists. One possible signature from a simulated proton-proton collision that would demonstrate the Higgs boson’s existence .The Higgs boson is believed to decay almost immediately after such a collision into two jets of hadrons (composite particles made of subatomic elementary particles held together by strong nuclear forces) and two electrons, . In December 2011, two experiments at the LHC independently reported that their data hint that the Higgs particle probably exists with a mass of about 133 proton masses. The range of mass for the Higgs particle is now thought to have been narrowed considerably to between approximately 122 and 138 protons. It is expected that the LHC will have a definite answer by the end of 2012.
