Hopes are rising that a previously unknown particle has been discovered by the Large Hadron Collider, the particle accelerator that lies under the France-Switzerland border near Geneva. The LHC was ...

Weak bosons are elementary particles that mediate weak interactions in particle physics. Weak bosons were predicted to exist theoretically in 1968, and their existence was confirmed in 1983 by the ...

There’s something amiss with a mass. A new measurement of the mass of an elementary particle, the W boson, has defied expectations. The result hints at a possible flaw in physicists’ otherwise ...

In the 1990s, the Liquid Scintillator Neutrino Detector (LSND) in Los Alamos, New Mexico, found a weird anomaly during its experiments on tiny elementary particles called neutrinos. It found far more ...

The Large Hadron Collider, the world's most powerful atom smasher, may be only months away from finding a new elementary particle -- a sign of a new force in nature ...

In a weak moment, researchers have found an unexpected asymmetry in particle production that could hint at exotic physics. The tentative evidence, announced August 21, could be the fingerprint of a ...

The results of a high-profile Fermilab physics experiment appear to confirm strange 20-year-old findings that poke holes in the standard model, suggesting the existence of a new elementary particle: a ...

Physicists have found that an elementary particle called the W boson appears to be 0.1% too heavy — a tiny discrepancy that could foreshadow a huge shift in fundamental physics. The measurement, ...

Scientists reviewed three experiments that hint at a phenomenon beyond the Standard Model of particle physics, outlines a new report. To anyone but a physicist, it sounds like something out of "Star ...

The Higgs particle can disintegrate into particles of dark matter, according to a new model that is being tested at the particle physics laboratory Cern. GENEVA: The Higgs particle can disintegrate ...
