Physicists know that their elegant theoretical description of forces and particles — the standard model of particle physics — must be incomplete, because there are a host of phenomena it cannot ...

Scientists working at CERN’s Large Hadron Collider may be seeing the strongest hints yet of physics beyond the Standard Model — the decades-old theory that explains the fundamental particles and ...

An unexpected behavior in a particle decay seems to disagree with the predictions of the Standard Model, despite its high ...

Scientists spent decades chasing signs of a mysterious new force hidden inside the muon, one of nature’s strangest particles.

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 ...

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 ...

No one has ever probed a particle more stringently than this. In a new experiment, scientists measured a magnetic property of the electron more carefully than ever before, making the most precise ...

Breaking the rules is exciting, especially if they have held for a long time. This is true not just in life but also in particle physics. Here the rule I'm thinking of is called “lepton flavor ...

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 ...
