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 ...
The pressure inside the particles that make up every atom in the universe could be greater than the pressure inside the densest stars, according to a new measurement. Scientists at Jefferson Lab in ...
Measuring up: an electron scattering experiment yields a small proton radius. (Courtesy: Jefferson Lab) For nearly a decade the size of the particle that makes up the bulk of the universe’s visible ...
