![]() We have reached a milestone in our understanding of nature, said CERN Director General Rolf Heuer. A more exotic version of the Higgs particle could be a bridge to understanding the 96% of the universe that remains obscure. ![]() All the matter that we can see, however, appears to be no more than about 4% of the total. Are its properties as expected for the long-sought Higgs boson, the final missing ingredient in the Standard Model of particle physics? Or is it something more exotic? The Standard Model describes the fundamental particles from which we, and every visible thing in the universe, are made, and the forces acting between them. The next step will be to determine the precise nature of the particle and its significance for our understanding of the universe. A more complete picture of todays observations will emerge later this year after the LHC provides the experiments with more data. Publication of the analyses shown today is expected around the end of July. They are based on data collected in 20, with the 2012 data still under analysis. The results presented today are labelled preliminary. With all the necessary caution, it looks to me that we are at a branching point: the observation of this new particle indicates the path for the future towards a more detailed understanding of what were seeing in the data. We stated last year that in 2012 we would either find a new Higgs-like particle or exclude the existence of the Standard Model Higgs. Its hard not to get excited by these results, said CERN Research Director Sergio Bertolucci. The implications are very significant and it is precisely for this reason that we must be extremely diligent in all of our studies and cross-checks." We know it must be a boson and its the heaviest boson ever found, said CMS experiment spokesperson Joe Incandela. "The results are preliminary but the 5 sigma signal at around 125 GeV were seeing is dramatic. The outstanding performance of the LHC and ATLAS and the huge efforts of many people have brought us to this exciting stage, said ATLAS experiment spokesperson Fabiola Gianotti, but a little more time is needed to prepare these results for publication. We observe in our data clear signs of a new particle, at the level of 5 sigma, in the mass region around 126 GeV. Both experiments observe a new particle in the mass region around 125-126 GeV. © 2012 CERNĬERN experiments observe particle consistent with long-sought Higgs bosonĪt a seminar held at CERN today as a curtain raiser to the years major particle physics conference, ICHEP2012 in Melbourne, the ATLAS and CMS experiments presented their latest preliminary results in the search for the long sought Higgs particle. On 4 July, 2012, the ATLAS experiment presented a preview of its updated results on the search for the Higgs Boson. The live video from CERN is no longer available. ![]() He spoke after two independent teams at CERN said they have both "observed" a new particle. Rolf Heuer, director of the European Center for Nuclear Research, or CERN, says "we have a discovery" of a new subatomic particle, a boson, that is "consistent with a Higgs boson." Update: The head of the world's biggest atom smasher says they have discovered a new particle that is consistent with the long-sought Higgs boson known popularly as the "God particle," which is believed to give all matter in the universe size and shape ![]() It has been creating high-energy collisions of protons to investigate dark matter, antimatter and the creation of the universe, which many theorize occurred in a massive explosion known as the Big Bang. The second team was just starting to present its evidence before a packed auditorium, where scientists broke into applause intermittently.įabiola Gianotti, leader of the second team of some 3,000 scientists, known as ATLAS, said it also has observed some "beautiful" events in CERN's atom smasher, the $10 billion Large Hadron Collider on the Swiss-French border. ![]() He described the data as consistent with the elusive Higgs boson, whose existence was predicted decades ago to help explain how the universe works, but stopped short of definitively declaring discovery of the Higgs boson. Joe Incandela, leader of one of the teams known as CMS, told scientists at the European Center for Nuclear Research, or CERN, that his team of 2,100 scientists has "observed" a new particle that is a boson the same type of particle as the long-sought Higgs boson, popularly referred to as the "God particle."

Physicists celebrate evidence of particle One of the two independent teams at the world's biggest atom smasher said Wednesday it has found strong evidence of a new subatomic particle that looks like the one believed to give all matter in the universe size and shape. ![]()
