The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...

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 ...

In the mid-1930s, physicists thought they knew all the subatomic particles of nature – the proton, neutron, and electron of the atom. However, in 1936 the muon was discovered – a new particle having ...

On July 4, 2012, researchers at the Large Hadron Collider (LHC) in Switzerland announced with great fanfare that they had successfully detected the Higgs boson, the manifestation of the mechanism that ...

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 ...

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 ...

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 ...

Editor’s Note: Lawrence M. Krauss is director of the Origins Project at Arizona State University and the author, most recently of, “A Universe from Nothing: Why There is Something Rather than Nothing” ...

No one has ever probed a particle more stringently than this. In a new experiment, scientists measured a magnetic property of the electron more carefully than ever before, making the most precise ...

Scientists at CERN in Switzerland have announced the discovery of a new elementary particle, the first new particle since the Z boson was discovered way back in 1983. Curiously, CERN isn't calling ...

THE STANDARD MODEL of particle physics—completed in 1973—is the jewel in the crown of modern physics. It predicts the properties of elementary particles and forces with mind-boggling accuracy. Take ...
