For a start it is worth noting that the mass in quantum mechanics has unusual features.It is not a fundamental value and gives the role of energy, which is connected via Einstein's famous equation E = mc ^ 2.Therefore, the mass of elementary particles devoid of the usual properties and is measured not quite usual in electron volts (eV), more precisely in the mega (MeV) and GeV (GeV).

history search for the Higgs boson has several notable steps.The first people to make a serious attempt to catch boson, scientists have been working on the LEP, the Large Electron-Positron Collider (not to be confused with the LHC, the Large Hadron Collider, which w
as built on the same spot, but later).After completing the experiments in 2001, they found that the minimum mass of the supposed "God particle" - 114.4 GeV.

In 2008, in search of help came from an unexpected source: the Russian and German physicists got boson mass range, analyzing cosmological data: 136-185 GeV.In 2011 finalized the Tevatron collider, located in Illinois, USA, and its final results provided by the autumn of that year, was the information that the mass of the Higgs boson is in the range 115-135 GeV.

Meanwhile, the search for Higgs held at the Large Hadron Collider, and in December 2011, scientists have provided interim results of their work.Physicists from the collaboration ATLAS (so-called one of the two big collider detectors) announced for the existence of a particle with a mass in the region 116-130 GeV, and scientists from the CMS (the second largest detector) - in the 115-127 GeV.

Finally, July 4, 2012, scientists from the LHC held an open seminar, which announced that they are more likely to found a new particle, which can be regarded as the Higgs boson.Its weight - 126 GeV.
