Historic Milestone: CERN Discovers Higgs-like Boson

http://facebook.com/ScienceReason ... New particle observed at LHC! CERN Physicists are sure they have found a boson particle -- but is it the long-sought Higgs boson of the Standard Model? The ATLAS and CMS experiments at CERN presented their latest results in the search for the long-sought Higgs boson. Both experiments see strong indications for the presence of a new particle, which could be the Higgs boson, in the mass region around 126 gigaelectronvolts (GeV). --- Please SUBSCRIBE to Science & Reason: • http://www.youtube.com/FFreeThinker • http://www.youtube.com/ScienceTV • http://www.youtube.com/Best0fScience • http://www.youtube.com/RationalHumanism --- CERN experiments observe particle consistent with long-sought Higgs boson At a seminar and a press conference held at CERN on 4 July 2012 as a curtain raiser to the year's 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. Both experiments observe a new particle in the mass region around 125-126 GeV. "We observe in our data clear signs of a new particle, at the level of 5 sigma, in the mass region around 126 GeV. 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." "The results are preliminary but the 5 sigma signal at around 125 GeV we're seeing is dramatic. This is indeed a new particle. We know it must be a boson and it's the heaviest boson ever found," said CMS experiment spokesperson Joe Incandela. "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." "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 --- CERN, the European Organization for Nuclear Research, is the world's leading laboratory for particle physics.

CERN Higgs Boson Discovery Seminar/Lecture

Director General of CERN, Rolf Heuer, and the head scientists from the ATLAS and CMS at CERN in Geneva gives a conference and lecture on the discovery of the Higgs Boson at a rest mass energy of 126.5 GeV at a 4.9 confidence level (the maximum limit being 5) . This confidence level, in experimental physics, constitutes a discovery with 98% probability of certainty, making it the first true discovery of the Higgs Boson in human history. The bump in the energy spectrum observed at 125GeV contained a bump known with 99.9997% certainty. Since the observed Higgs mass lies between 115--130 GeV, this rules out the minimal Standard Model Higgs expected at 141 GeV. This means that it is a Higgs-like Boson! The Higgs seen at 125.5 GeV is at 3.8 sigma confidence level for the 4-lepton channel, the so-called "Golden Channel" of 4-leptons, created by the Higgs decaying into 2 Z-Boson Intermediates and those decaying into 4-leptons, 2-leptons per Z-Boson. These Leptons are Muons, detected by the Compact Muon Solenoid (CMS) detector. The same channel leads to a 3.2 confidence level with the look elsewhere effect taken into account. The Z-boson and photon channel integrated gives 5 sigma, the highest level possible with no significant errors. The W-channel gives 1.5 sigma confidence channel, so it is definitely meeting the double blind trials of a "Well-behaved" Higgs. Its a good boson for a Higgs candidate, it does as the Higgs should. The discovery from the various decay channels detected, the Boson discovered was most likely a "New Boson" or at least a "Higgs-like" Boson at 125.3 +/- 0.6 GeV at 4.9 sigma confidence level. This makes it a significant scientific discovery. The minimalist models of the Standard Model predict that the Higgs mass ought to be at about 141 GeV. So a 125 GeV model is a problem, theoretically, and leads to many problems like an unstable vacuum at energies much lower than the Planck scale. The Physics obtained from this discovery will most likely be new physics that will help us understand electroweak symmetry breaking but it also seems more and more likely that we are beginning to observe the effects of Supersymmetry for the first time aswell. Supersymmetric models are our best bet in this situation for the Boson discovered, for which it behaves like the Higgs Boson should. The Boson Detected with the square root of its action being at 8TeV has a Lagrangian Density of about 5 femtobarns (5 x 10^-9 barns), since 1 barn = 100 femtometers^2 this means the Higgs cross-section is only 5 x 10^-43 meters squared. Experimentally however it is a great triumph and a powerful discovery, the data obtained from this event through rigorous experimental and computational techniques will be studied and scrutinized as normal but now we know where to go from here. The Boson is here to stay and the work is going to begin on mastering it. Considering that it was found in the last energy region searched, this last piece of the jigsaw is deservedly put in its rightful place. The full picture will change everything.

Kepler 22b New Planet Discovered Earth like Characteristics -- News Story

Kepler-22b New Planet With Earth-Like Characteristics Discovered In Habitable Zone thoughts NASA's Kepler Confirms Its First Planet in Habitable Zone of Sun-like Star: Kepler 22-b (5/12/2011) thoughts NASA's Kepler Mission Announces Latest Planetary Discovery thoughts This is amazing news according to reports NASA announced the discovery of Kepler-22b this is great the first planet the Kepler spacecraft has discovered in the habitable zone, an area with a distance from a star where temperatures will permit the existence of liquid water.Reports say the discovery of Kepler-22b which is 600 light-years away from Earth, brings scientists one step closer to finding a planet that could possibly harbor life Earth may not be the only one This is a major milestone on the road to finding Earth's twins Kepler's results continue to demonstrate the importance of NASA's science missions, which aim to answer some of the biggest questions about our place in the universe Kepler-22b has several Earth-like characteristics according to reports The new planet's temperature is around 72 degrees Fahrenheit and its radius is 2.4 times Earth's. The planet completely orbits its star, which is similar to our sun, every 290 days, just 75 days shy of an Earth year Reports say that the National Optical Astronomy Observatory announced the discovery of Kepler-21b, a new planet with a radius 1.6 times Earth's. But unlike Kepler-21b, which is only about 3.7 million miles away from its sun and is therefore a scorching 2,960 degrees Fahrenheit, Kepler-22b is about 79 million miles from its sun, coming in at a pleasant 72 degrees. it's not yet clear if Kepler-22b is composed or rock, gas or liquid according to reports. Scientists use the Kepler spacecraft to discover new planets by analyzing extremely faint dips in light from far-away stars. These "dips" occur each time the planet passes between the Kepler and its sun, therefore obstructing the star's light. In order for a planet to be confirmed, scientists must observe the celestial body orbit its sun three times according to sources Kepler-22B takes 290 days to orbit its sun, it took nearly three Earth years for scientists to confirm that it was a planet.
