Physicists at the U.S.-based Fermilab have produced a new particle that is a heavier relative of the neutron. The Batavia, Illinois atom smasher found the neutral Xi-sub-b by smashing particles together around a 4-mile ring at near light speed.  Physicists knew the particle existed, but it is the first time researchers have observed it firsthand.  Measuring the properties of particles like the neutral Xi-sub-b allows physicists to understand how quarks interact to form matter....

A senior physicist said on Monday that the CERN's Large Hadron Collider (LHC) set a new record in its quest to pinpoint the elusive particle known as the Higgs Boson. "Last night, a symbolic frontier was crossed," said Michel Spiro, president of the board of the European Organization for Nuclear Research (CERN), according to the AFP news agency. The rate of sub-atomic collisions at the world's biggest particle collider has multiplied 10-fold in the last month. The 16.9-mile tunnel is...

Physicists may finally be close to answering one of the biggest mysteries in science "“ whether or not a "God particle", or Higgs boson, exists. In theory, the Higgs boson is responsible for mass, without which there would be no gravity and no universe. The notional sub-atomic Higgs particle was named after British physicist Peter Higgs, who proposed its existence in 1964. Until now, the massive energies required to extract the Higgs from the building blocks of matter have not been...

Researchers use the NSF-supported Ranger supercomputer to explore alternative particle theories As the Large Hadron Collider (LHC) ramps up the rate and impact of its collisions, physicists hope to witness the emergence of the Higgs boson, an anticipated, but as-yet-unseen, fundamental particle that scientists believe gives mass to matter. The Higgs boson is a central component of the "standard model," a theory that defines the relationships between the forces of the universe. But, what if...

Scientists at CERN's Large Hadron Collider (LHC) played down claims of a significant discovery, after a leaked memo hinted that the elusive "God particle" may have been found. Experts say speculation of the dramatic finding for the Higgs boson particle is premature. The leak surfaced online and then was spread rapidly among the scientific community. A spokesman for CERN -- the European Organization for Nuclear Research -- confirmed that the note was authentic. But he told BBC News that the...

Scientists outline a test for the theory, which, if proven, would address major problems in particle physics Did the early universe have just one spatial dimension? That's the mind-boggling concept at the heart of a theory that University at Buffalo physicist Dejan Stojkovic and colleagues proposed in 2010. They suggested that the early universe -- which exploded from a single point and was very, very small at first -- was one-dimensional (like a straight line) before expanding to include two...

According to an AFP report, data from the U.S. Department of Energy's Fermi National Accelerator Laboratory (Fermilab) may have revealed a new elementary particle, or potentially a new force of nature. The new find offers clues to the persistent riddle of mass and how objects obtain it, which is one of the most sought-after answers in all of physics. Experts, however, caution that more analysis is needed to uncover the true nature of the discovery. "There could be some new force beyond the...

By David Salisbury, Vanderbilt University If the latest theory of Tom Weiler and Chui Man Ho is right, the Large Hadron Collider "“ the world's largest atom smasher that started regular operation last year "“ could be the first machine capable of causing matter to travel backwards in time. "Our theory is a long shot," admitted Weiler, who is a physics professor at Vanderbilt University, "but it doesn't violate any laws of physics or experimental constraints." One of the major...

CERN scientists announced on Monday that they have staged their first speed-of-light particle collisions of the year over the weekend. "It started up well, with stable beams. We are even a little ahead of schedule after the winter break," spokesman James Gillies told Reuters. The $10 billion project's leading physicist, Oliver Buchmueller, told Reuters that the top priority in 2011 and 2012 would be finding evidence of super-symmetry, extra dimensions, dark matter, black hole production and...

Researchers working at the Large Hadron Collider (LHC) said they expect to discover the elusive Higgs boson particle by the end of 2012. If the LHC does not show any evidence of the mysterious particle during this run, physicists said that they may have to significantly alter their views of physical laws. The Higgs boson particle explains why other particles have mass, but it has not yet been observed by physicists. The LHC is housed in a 16-mile long tunnel under the French-Swiss border....
