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 ...

Physicists at CERN’s Large Hadron Collider have uncovered new hints that certain particle decays may not behave as the ...

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 ...

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

Scientists have inched a step closer to solving an enduring mystery in physics — why the universe contains any matter at all — thanks to a newly combined analysis from two of the world's leading ...

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 ...

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 ...
