Europe found that suspected the credibility of the "God particle" of up to 99.99994%
"Standard model" theory of modern physics of elementary particles, the last undetected elementary particle may be found!
Yesterday from the European Hadron Collider two experimental groups, respectively, announced they observed a new boson. Has always been strict and conservative physicist is not very conclusive tone announced, "We have found the Higgs boson, but said" We found a very 'like' the Higgs boson, new particles; However, experimental results integrated together, the results only beyond the 5 error standard error, the early achievement of the 99.99994% confidence level.
Conference the end of 44 years ago predicted the existence of the Higgs boson British physicist Peter Higgs in tears, said: "actually occurred in my life so incredible."
The last particles of the standard model is found
This is a historic milestone. The Standard Model of modern physics to establish, with the most basic law of the universe, and will thus further confirmation and development.
For modern physicists, no matter how "flattering" the Higgs boson does not seem excessive. 1993, Nobel Laureate, experimental particle physicist Leon Lederman, he called the "God Particle: If the universe is the answer, then what is appropriate?" Popular science book, even to the said "God particle".
So, what is the Higgs boson?
Simply put, Peter Higgs to the assumption that the Higgs boson exists, perfectly explains the source of the material quality. And "quality", which Newton did not complete the puzzle. Higgs proposed that the other particles in the Higgs boson constitutes a "sea" cruising in the Higgs field by its role of inertia, and the resulting quality. Later, all the particles in the framework of the three kinds of forces outside of the gravitational interactions, unification under the "standard model", built into the wider world.
This set is called "particle physics standard model theory predicted the existence of 62 kinds of elementary particles, the particle have been experimentally confirmed, and only the most critical Higgs boson remains undiscovered.
Decades, numerous scientists have been devoted to proving the existence of this particle, it is spin zero, the quality of other particles in its role, which can lay the foundation for the interpretation of the formation of the universe. Therefore, within the in-depth material, to find the Higgs boson, it proved the last century human physicists are working hard to establish the standard model is not wrong, which explain the basic law of the universe.
Many experts believe that, if it is really able to find direct evidence of the Higgs boson exists, the discovery of Nobel Prize-winning. In September 2008, the European Organization for Nuclear Research Centre was officially launched the world's largest Large Hadron Collider (LHC). From concept to completion, LHC took nearly 20 years at a cost of approximately $ 6,000,000,000, which attracted about 7000 scientists and engineers from over 80 countries and regions to participate. IHEP research fellow Paul Chan and his colleagues, as well as Peking University and other 10 Chinese research institutes and university researchers are involved in the core of research - to find the "Higgs boson".
In December 2011, CERN announced that the signs of the Higgs boson from hadron collider data. In early July, the Fermi National Accelerator Laboratory in the United States also claimed that close to confirm the existence of the "God particle". Yesterday, CERN announced the latest results, and will look for the "God particle" process to a climax.
Miao Li, researcher at the Institute of Theoretical Physics, Chinese Academy of Sciences yesterday and his colleagues in the years to watch the webcast of the conference CERN. He is expected in the next six months, the Large Hadron Collider will be more experimental, resulting in more data validation, to support today's discovery.
