OAK RIDGE, Tenn. — Examining the smallest parts of the universe often takes the biggest kinds of equipment. At Oak Ridge National Laboratory, a unique piece of equipment the size of a building is ...

In the world of nuclear physics, protons often take the spotlight. But now, for the first time, the neutron has stepped into it. A recent experiment using the U.S. Department of Energy’s Jefferson Lab ...

When atomic nuclei collide at nearly the speed of light, they unleash something extraordinary. Protons and neutrons break apart, freeing quarks and gluons, the tiniest building blocks of matter. In ...

A new measurement of the strong nuclear force, which binds protons and neutrons together, confirms previous hints of an uncomfortable truth: We still don’t have a solid theoretical grasp of even the ...

Physicists used MINERvA, a Fermilab neutrino experiment, to measure the proton’s size and structure using a neutrino-scattering technique. For the first time, particle physicists have been able to ...

Protons are the basic building blocks of matter. Together with neutrons, they form atomic nuclei. These minute, positively charged particles have an antimatter counterpart, antiprotons. While the ...
