Scientists say there is less evidence of the existence of 'God particle'

International scientists trying to identify the Higgs boson, the greatest puzzle of modern physics, the evidence indicated that the existence of elementary particle, also known as the "God particle" which supposedly gives mass to objects, is increasingly tenuous.

"Right now, we see no evidence of the Higgs boson in the region of low mass in what is likely to be," he said on Monday physicist Howard Gordon, deputy director of program operations U.S. ATLAS Experiment.
The ATLAS Experiment is one of the five particle detectors (along with ALICE, CMS, TOTEM and LHCb) in the Large Hadron Collider (LHC), the new particle accelerator at the European Council for Nuclear Research (CERN) in Switzerland.

In July, physicists announced in a European conference that one of the LHC experiments had resulted in promising evidence about the presence of the Higgs boson, a time when the quest to identify the particle entered the homestretch, with results expected later 2012. If one exists, the Higgs boson, sometimes described as the "God particle" because it is a mystery and at the same time, a powerful force of nature, represents the last piece of the Standard Model of physics.

Gordon told AFP that the evidence in July, which were of little significance now, "are even less significant." However, physicists are not willing to rule out the possibility that the Higgs boson exists, the cyclotron has yet to examine a large amount of data in the low-frequency spectrum.

"I think it was always a possibility that the Higgs boson does not exist, but I do not think we are ready to say this right now," he said.

A statement that summarizes the most recent data, was circulated at a conference in Mumbai, India, indicating that the experiments "ATLAS and CMS to exclude a 95% certainty the existence of a Higgs boson in most of the 145 mass region 466 GeV. "

The CERN research director, Sergio Bertolucci, said the scientists hope to learn more about the existence of elementary particle in the next year. "If the Higgs boson exists, the LHC experiments will find it soon. If the experiments do not find, its absence indicates the path of a new physics," said Bertolucci.

The LHC, located near Geneva, Switzerland, was created to make the acceleration of protons at nearly the speed of light and then destroy them in labs where the detectors record its hectic subatomic debris. The process temperature reaches 100 thousand times higher than those of the Sun, fleetingly emulating the conditions that prevailed in split-second after the "Big Bang" that created the universe some 13.7 billion years.

"Whatever the final verdict on the Higgs boson, we are living in very exciting times for everyone involved in the search for new physics," concluded the spokesman for CMS, Guido Tonelli. CERN and discussion on the "God particle" was recently the subject of the plot of the book "Angels and Demons" by Dan Brown, then taken to the movies.
