American scientists have found the "God particle"

The most convincing evidence to date of the existence of the Higgs boson found the staff of the US National Laboratory Fermi name. Higgs Boson - an elementary particle predicted by theory, the discovery of which will allow scientists to unravel the mystery of the formation mechanism of the masses.

The Higgs boson is called "God particle." The discovery of "God particle" should prove dominant in modern science standard model of interaction between elementary particles, ITAR-TASS reported. [Next]

The discovery was made by studying the results of collision of particles in the largest US circular collider "Tevatron", whose work was ever stopped in October 2011. It was the second power unit of this kind after the Large Hadron Collider (LHC) of the European Centre for Nuclear Research (CERN), put into operation in March 2010, on the French-Swiss border. "Tevatron" has been put into operation in 1983. His underground ring stretching 6, 28 kilometers allowed at high speeds collide protons and antiprotons.

"Data" Tevatron "strongly suggest the existence of the Higgs boson, but for the recognition of scientific discovery will need the results of experiments at the Large Hadron Collider in Europe" - said the representative of the Fermi lab named Rob Rouzer.

According to American scientists, the likelihood that they observed exactly the Higgs boson and not some other particle that is more than 99, 8%. Meanwhile, in order to be confident in the discovery, scientists need to achieve a degree of probability which is defined in scientific usage as "five sigma". It means that the probability that the particle is found Higgs boson, is 99, 99995%.

According to the researchers, the discovery of this particle should be the largest discovery in the field of knowledge of the laws of the universe over the past decade. Search for the Higgs boson has been one of the main objectives of the construction of the Large Hadron Collider.

Scientists believe that after the Big Bang, which started the universe 13, 7 billion years ago, the power generating Higgs boson, has given rise to the formation of galaxies, stars and planets from the original chaos.

If the Higgs boson is not found, it would prove the limitations of the Standard Model. As a result, there will need to find an alternative theory of the origin of mass in accordance with the so-called new physics.

The Higgs boson, the Higgs boson - the theoretically predicted elementary particle elementary boson quantum of the Higgs field, a need arises in the Standard Model Higgs mechanism as a result of spontaneous electroweak symmetry breaking. By construction, the Higgs boson is a scalar particle, ie has zero spin. Peter Higgs postulated in its fundamental articles published in 1964. [1] [2] In the framework of the Standard Model is responsible for the mass of elementary particles.

The Higgs boson - the latter has not yet found a particle of the Standard Model. Higgs particle is so important that the title of the book by Nobel laureate Leon Lederman (The God Particle: If the Universe Is the Answer, What Is the Question? (Eng.)), It is called «god particle» (God particle or particle-god) < br />
Scientists at CERN are also going to announce the discovery of the Higgs boson July 4, 2012.
