Physicists know that their elegant theoretical description of forces and particles — the standard model of particle physics — ...

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 ...

Add Yahoo as a preferred source to see more of our stories on Google. This image provided by the Fermi National Accelerator Laboratory shows the ring-shaped track that scientists used to study tiny ...

Physicists at Colorado State University have measured the radius of a hydrogen proton with ...

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 ...

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

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 ...

Researchers at the Max Planck Institute for Quantum Optics (MPQ), Garching, in collaboration with Prof. Dr. Randolf Pohl from the Institute for Physics at Johannes Gutenberg University Mainz (JGU), ...

NEW YORK – 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 know ...
