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 2024, the T2K Collaboration started to collect new neutrino data following several upgrades to the experiment that included new types of detectors. One of these, called SuperFGD, has a mass of ...

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 ...

The National Academies of Sciences, Engineering, and Medicine are private, nonprofit institutions that provide expert advice on some of the most pressing challenges facing the nation and world. Our ...

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 ...

In the first joint result from the world's two leading particle colliders, scientists have determined the mass of the heaviest elementary particle, the top quark. The measurement was made using the ...

New scientific results confirm an anomaly seen in previous experiments, which may point to an as-yet-unconfirmed new elementary particle, the sterile neutrino, or indicate the need for a new ...

An experiment at the Fermi National Accelerator Laboratory near Chicago has detected far more electron neutrinos than predicted — a possible harbinger of a revolutionary new elementary particle called ...

Scientists have determined the mass of the heaviest elementary particle, the top quark. The measurement was made using the Large Hadron Collider (LHC) at CERN in Geneva, Switzerland, and the Tevatron ...

THE name “negative electron” was applied to the elementary particle of negative electricity after the experimental evidence for the variation of its mass with velocity had generally convinced ...
