Scientists have used CERN's Large Hadron Collider (LHC) to uncover what they say is an entirely new type of particle, dubbed ...

The atomic nucleus is made up of protons and neutrons, particles that exist through the interaction of quarks bonded by gluons. It would seem, therefore, that it should not be difficult to reproduce ...

Scientists are holding up a 'mirror' to protons and neutrons to learn more about the particles that build our visible universe. The MARATHON experiment has accessed new details about these particles' ...

Physicists just discovered a brand-new particle that appears to be an exotic cousin to the protons and neutrons that make up ...

An experiment at the Brookhaven National Laboratory (BNL) in the United States provides new insights into the strong interaction that holds neutrons and protons together inside atomic nuclei 1.

The new particle, named Xi-cc-plus, carries two heavy charm quarks and is about four times heavier than an ordinary proton.

An international team of researchers recently measured the lifetime of a neutron outside of an atomic nucleus with extraordinary precision. By their measurements, the neutron survived for 14.629 ...

A team of scientists, including four at The Johns Hopkins University, has discovered two new subatomic particles, rare but important relatives of the familiar, commonplace proton and neutron. Named ...

Inside each proton or neutron there are three quarks bound by gluons. Until now, it has often been assumed that two of them form a "stable" pair known as a diquark. It seems, however, that it's the ...

Physicists have found the strongest sign yet of a fabled four of a kind. For six decades, researchers have hunted for clusters of four neutrons called tetraneutrons. But evidence for their existence ...

When most of us picture an atom, we think about a small nucleus made of protons and neutrons orbited by one or more electrons. We view these electrons as point-like while rapidly orbiting the nucleus.
