What is the Higgs Boson? Has it been discovered yet?

http://www.facebook.com/ScienceReason ... John Ellis, theoretical physicist: What is the Higgs Boson? Has it been discovered yet? CERN experiments observe particle consistent with long-sought Higgs boson. --- Please subscribe to Science & Reason: • http://www.youtube.com/Best0fScience • http://www.youtube.com/ScienceTV • http://www.youtube.com/FFreeThinker • http://www.youtube.com/RationalHumanism --- "It's hard not to get excited by these results," said CERN Research Director Sergio Bertolucci. "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. 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 we're seeing in the data." The results presented today are labelled preliminary. They are based on data collected in 2011 and 2012, with the 2012 data still under analysis. Publication of the analyses shown today is expected around the end of July. A more complete picture of today's observations will emerge later this year after the LHC provides the experiments with more data. The next step will be to determine the precise nature of the particle and its significance for our understanding of the universe. 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. All the matter that we can see, however, appears to be no more than about 4% of the total. A more exotic version of the Higgs particle could be a bridge to understanding the 96% of the universe that remains obscure. "We have reached a milestone in our understanding of nature," said CERN Director General Rolf Heuer. "The discovery of a particle consistent with the Higgs boson opens the way to more detailed studies, requiring larger statistics, which will pin down the new particle's properties, and is likely to shed light on other mysteries of our universe." Positive identification of the new particle's characteristics will take considerable time and data. But whatever form the Higgs particle takes, our knowledge of the fundamental structure of matter is about to take a major step forward. • http://press.web.cern.ch/press/PressReleases/Releases2012/PR17.12E.html --- Tags: higgs boson cern lhc atlas experiments found observed new fundamental particle physics standard model forces universe properties mysteries data july 2012 .

The discovery of the Higgs Boson? Garrett Lisi explains

Following the CERN announcement, Theoretical physicist Garrett Lisi explains the discovery of the Higgs Boson particle by CERN scientists. Previously, LHC results have strongly signaled the existence of a Higgs with a mass of 125 gigaelectronvolts (GeV), or roughly 125 times more massive than the proton.
