“There’s a lot of meanings for ‘small,’” says Janet Conrad, a particle physicist at the Massachusetts Institute of Technology ...

Theorized for decades leading up to its discovery on July 4, 2012, the Higgs boson is a subatomic particle that has the power to either confirm or shatter physics’ most comprehensive theory to ...

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 ...

Researchers are trying to explain their anomalous findings. Their larger experiment is an ongoing investigation of CP ...

Forte and colleagues fed 35 years of data from particle accelerators, including the world’s largest and most powerful machine of this kind, the LHC, to a computer algorithm that pieces proton ...

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 found ...

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

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 ...
