For decades, physicists have searched in vain for exotic bound states comprising more than three quarks. Experiments have now shown that, in fact, such complex particles do exist in nature. The ...

There are six types of quarks. Up and down quarks are found in protons and neutrons. The other four (charm, strange, top, and bottom) are only seen after very energetic events, as they are not stable.

Bottom quarks. Bottom quarks are created during high-energy collisions between particles. The bottom quark is one of six quarks. Together with the top quark it is one of the heaviest quarks.

Just because they deal with understanding the fundamental nature of how the universe formed doesn’t mean that scientists can’t have a little fun with their work. Researchers took a ligh… ...

Quarks all have what’s known as a color-charge, where in addition to electric charges, they have a color: red, green, or blue, while the anti-quarks can be anti-red, anti-green, or anti-blue.

Each contains six quarks. (Courtesy: Bo Wang/Hebei University) Multiple hexaquarks – strongly interacting hadronic particles comprising six quarks – are likely to exist, according to a new theoretical ...

There are six kinds, or "flavors," of quarks: up, down, top, bottom, strange and charm. A neutron is composed of two down quarks and one up quark. If you squish too many atoms together, ...

This process, called fragmentation, gives physicists clues about how quarks behave when they’re released from the tight grip of the strong nuclear force. Now here’s where the symmetry jumps in.

Bottom quarks. Bottom quarks are created during high-energy collisions between particles. The bottom quark is one of six quarks. Together with the top quark it is one of the heaviest quarks.
