What is the mass of the Higgs boson

July 4, 2012 the scientific world celebrated the great victory. On this day, scientists working on the Large Hadron Collider (LHC), announced that they are more likely to found the famous "God particle" - the Higgs boson, whose existence was predicted in the 70s. last century. Finding the particle itself, the scientists were able to determine and its mass.

What is the mass of the Higgs boson

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). Search History of 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 was built on the same spot, but later). After completing the experiments in 2001, they found that the minimum mass of the alleged "god particle" - 114.4 GeV. In 2008, assistance in finding came from an unexpected source: the Russian and German physicists have received a range of boson mass by analyzing cosmological data: 136-185 GeV. In 2011 finalized the Tevatron accelerator, located in Illinois, USA, and its final results provided by the autumn of the same year, was the information that the mass of the Higgs boson 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 ATLAS collaboration (so called one of the two big collider detectors) announced the existence of signs of a particle with a mass in the region of 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 have announced that they are more likely to found a new particle, which can be considered as the Higgs boson. Its weight - 126 GeV.
