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 ...
A new theory-based approach provides access to the minute transverse motion of quarks within protons. Nuclear physicists have developed a new theoretical framework that allows them to calculate a ...
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 ...
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 ...

Using CERN’s Super Proton Synchrotron, researchers generated plasma fireballs to simulate blazar jets. The beams stayed ...
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 ...
The experiments at the Large Hadron Collider (LHC) detect rare events on a daily basis, but some are exceptionally rare, such ...
