Protons might be stretchier than they should be. The subatomic particles are built of smaller particles called quarks, which are bound together by a powerful interaction known as the strong force. New ...

Julie Roche, professor of physics at Ohio University, has been named a 2025 Fellow of the American Physical Society (APS), ...

Physics at the smallest scales is a challenge of observation: Particles are often fleeting, and the forces that govern their behavior are nearly imperceptible. But now, by exploiting decades-old data ...

For the first time, by studying quantum correlations between triplets of secondary particles created during high-energy ...

For almost a decade, physicists have been baffled by the so-called proton radium puzzle: using different methods of measurement, they obtained two numbers that are slightly yet significantly different ...

How big is a proton? This doesn’t sound like a very complicated question, but it’s one that turned out to have the potential to wreck a lot of modern physics. That’s because different methods of ...

STARKVILLE, Miss.—Research by Mississippi State scientists has helped resolve the decades-old “proton radius puzzle,” a question that for years has had physicists experimenting and theorizing to ...
