One of the four German films to feature in the main competition selection at this year’s Berlinale was The Elementary Particles by Oskar Roehler. The film is inspired by the 1998 novel of the same ...

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 ...

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 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 ...

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 discovery of different kinds of mesons with rest-masses spreading over a considerable range has brought about a fundamental change in the aspect of the problem of elementary particles. It looks as ...

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.
