To learn more about the nature of matter, energy, space, and time, physicists smash high-energy particles together in large accelerator machines, creating sprays of millions of particles per second of ...

Physicists know that their elegant theoretical description of forces and particles – the Standard Model – must be incomplete, ...

A tiny discrepancy in particle physics has loomed for decades as an exciting possible crack in one of science’s most ...

A neglected force produced by neutrinos and other particles helps atomic physics measurements align with predictions of the standard model.

NPR's Ayesha Rascoe speaks to Esra Barlas Yücel, a researcher at University of Illinois at Urbana-Champaign, about Fermilab's most precise measurements of the muon particle's magnetic wobble. It's ...

NEW YORK (AP) — Final results from a long-running U.S.-based experiment announced Tuesday show a tiny particle continues to act strangely — but that’s still good news for the laws of physics as we ...

Physicists have nailed a fiendishly difficult measurement — the mass of the fundamental particle the W boson. The result, from the CMS experiment at the Large Hadron Collider (LHC), is in line with ...

This image provided by the Fermi National Accelerator Laboratory shows the ring-shaped track that scientists used to study tiny particles called muons, July 20, 2023 in Batavia, Ill. (Ryan ...
