We may have glimpsed the Higgs boson, say Cern scientists

physicists have seen strong evidence for the Higgs boson exists, but a discovery company can not reach the end of 2012

scientists believe they have caught their first glimpse of the Higgs boson, a particle of God's call is supposed to support the operation of sub-atomic nature.

Fabiola Gianotti and Guido Tonelli was applauded by hundreds of scientists, because yesterday revealed evidence of the particle from the rubble of hundreds of billions of proton collisions inside the Grand Hadron Hadron Collider at CERN, the European Laboratory for Particle Physics near Geneva.

first postulated in the 1960s, the Higgs boson has become the most coveted prize in particle physics. Their discovery is one of the most important scientific advances of the past 100 years and see how elementary particles acquire their mass.

Although the results are inconclusive - the suggestions of the particle may disappear when more data is accumulated LHC next year -. What are the strongest evidence yet that the Higgs is there to be found

"We have reduced the region where the Higgs particle is more likely to be, and we see some signs of interest, but we need more data before we can draw definitive conclusions "said Gianotti, who heads the team working on the Atlas huge collider detector." It was a busy time, but a very exciting time. "

Finding the Higgs boson has been an important goal for the 10 billion pounds of LHC after a less powerful machine at CERN, called LEP failed to find the particle that is missing before closing the company in 2000.

The Higgs particle is the signature of a physics theory published six months apart in 1964. Peter Higgs of Edinburgh University, was the first to emphasize that the theory called the existence of the particle is missing.

Ben Allanach, a theoretical physicist at the University of Cambridge, said: "My personal feeling is that it is likely to have a kind of Higgs course, the discovery can not be officially called yet, but I feel in me. my heart just to see the precursor of a notice of discovery. "

Higgs theory, an invisible energy field, fill in the vacuum of space throughout the universe. When some particles move through the field to feel drag and weight gain thereafter. Others, such as particles of light, or photons, do not feel any resistance at all, and remain massless.

Without the field - or something to make your work - all the fundamental particles that weigh nothing and are thrown into the speed of light. It would be a disaster for the formation of atoms in the universe and spread early life as we know it.

• scientists have no hope of detecting the field itself, but the discovery of the Higgs boson would prove he exists.

While the field is thought to give mass to fundamental particles, including quarks and electrons (the two types of particles that make up the atoms), which represents only one or two percent of the weight of an atom of these, or any other everyday object. This is because most of the mass comes from the energy that binds all quarks inside atoms.

physicists hunt for the Higgs boson at the LHC to sift through a shower of subatomic debris that eject when protons collide in the machine near the speed of light. Most particles of the energy released in these microscopic fireballs is best known are identified by the giant collider detectors. Sometimes the collisions could create a Higgs boson, but it is expected to immediately disintegrate into small families. To find scientists to look for telltale "excesses" of the particles. They appear as bumps or peaks in the data.

Particle physicists use a "sigma" scale to assess the significance of the results, one to five years. One and two sigma results are not reliable because they come and go with the statistical fluctuations in the data. Three-sigma result as an "observation", while a five sigma result is sufficient to request a formal discovery. Less than one chance in a million d'un result of five sigma be a statistical fluke.
Gianotti Tonelli and led two separate teams - one with the ATLAS detector at CERN, the other with the laboratory Compact Muon Solenoid. In his seminar yesterday, a team reported a sudden 2.3 sigma in your data which can be a 126GeV Higgs boson weight, while the other reported a 1.9 sigma Higgs signal in a mass of about 124GeV. There is 1% chance that the result of the Atlas could be due to random fluctuation in the data.
