Without elementary particles, there'd be no X-Ray machines, no Internet and no electricity. Because some elementary particles penetrate matter without destroying it, they're a boon for scientific and ...

Some things are easier to achieve if you're not alone. As researchers from the University of Rostock, Germany have shown, this very human insight also applies to the most fundamental building blocks ...

In particle physics, data long outlives the detectors that generate it. A decade ago the 4,100-metric-ton Collider Detector at Fermilab (CDF) reached the end of its life and was shut down, stripped of ...

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 ...

Yesterday, we presented a comprehensive guide to the world of subatomic particles, exploring all the known elementary and composite particles. But now it’s time to put certainty to one side and ...

The Committee on Elementary-Particle Physics was convened by the National Research Council's Board on Physics and Astronomy to assess the field of elementary-particle physics as part of the survey ...

In the literal sense, nothing is simpler than an elementary particle: By definition, a particle is considered to be elementary only if there is no evidence that it is made up of smaller constituents.
