The scientists of the Large Hadron Collider, the discovery of a new particle, likely the long-sought Higgs boson, announced. The researchers of CERN, in the presentation is still a blow to the arm.
The discovery of the particle is apparent from analysis of the collisions in the Large Hadron Collider. That particle would, according to the researchers, the langgezochte Higgs-boson. From the results of the CMS team and the Atlas team, the two main detectors of the LHC, would the particle have a mass of about 125GeV. The probability that the observations on coincidence, is due to a significance of 4.9 sigma is only about 0.0001 percent.
Although still more analysis of the data is needed, the alleged particle of eur 125.3 GeV of the Higgs boson. The boson with a mass of about one hundred and thirty times that of a proton is the heaviest boson that is known. That mass would fit within the Standard Model, in which the Higgs boson is predicted, and it would explain why some particles have mass and others do not.
A group of scientists, including the Scotsman Peter Higgs, predicted in the sixties the existence of an elementary particle that is a crucial part to the current physical theories in the field of mass support. For example, the existence of the Higgs, for example, demonstrated why photons and electrons do have mass. The Higgs field by Higgs bosons is formed, would be the mechanism by which particles their mass from it.
At the end of december last year, CERN is already evidence for the Higgsdeeltje. Then there was a chance of one in a thousand, i.e. 3 sigma, that the measurements on the coincidence. From the analyzed data made CERN that particles with a mass of 115 to 130GeV the Higgs boson could be. Also in the American Tevatron-particle accelerator instructions were for the Higgs-boson found: they estimate the mass between 115 and 135GeV, which is consistent with the CERN findings.
The Large Hadron Collider is a particle accelerator where protons, lead ions and other particles are accelerated to nearly the speed of light. Two beams of particles travel in opposite directions in a ring of about 27 km long to detectors, CMS and Atlas, against each other to collide. In that collision the particles desintegrate into elementary particles, building blocks like quarks, leptons and bosons. The particles are only very briefly visible before they expire, what the observation very difficult. In the LHC, since the commissioning of millions of collisions detected.
