The peculiar wobble of a subatomic particle called a muon in a U.S. laboratory experiment is making scientists increasingly suspect they are missing something in their understanding of physics ...

A decade ago, the Large Hadron Collider, Earth's most powerful particle accelerator, proved the existence of an subatomic particle called the Higgs boson -- thought to be a fundamental building ...

Obituaries Peter Higgs, Nobel-winning physicist on a subatomic hunt, dies at 94 His theory, contingent on what became known as the Higgs boson, made the Standard Model of Particle Physics possible ...

Fermilab’s new measurement of subatomic muon particle challenges standard physics theories ...

The subatomic particles called neutrinos are famously elusive. But an unconventional trick could make a laser beam of the aloof particles.

Chinese particle physicists have announced evidence for a new subatomic particle found when the (J/psi) meson decays to a positive and negative pion pair. Although new subatomic particles are ...

GENEVA — Physicists are closing in on an elusive subatomic particle that, if found, would confirm a long-held understanding about why matter has mass and how the universe's fundamental building ...

At Fermilab, US physicists are refining their measurements of this subatomic particle—which has major implications for the Standard Model.
