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 ...

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, a research team from the University of Cologne has observed the electron capture decay of technetium-98, ...

New research conducted by nuclear physicists is using a method that connects theories of gravitation to interactions among the smallest particles of matter. The result is insight into the strong force ...

WASHINGTON, D.C., July 20, 2009 -- Proton therapy -- which uses beams of the subatomic particles to treat cancer -- is a hot topic at this year's American Association of Physicists in Medicine (AAPM) ...

CHAMPAIGN, Ill. — An international team of nuclear physicists has determined that particles called strange quarks do, indeed, contribute to the ordinary properties of the proton. Quarks are subatomic ...

A neutrino is one of the most well-known, and arguably most mysterious, particles in all of physics. This is because while they exist in vast quantities throughout the universe, they are also very ...

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 ...
