Quarks are elementary particles that are the building blocks of all visible matter in the universe. Explore them in more detail here.

By separately scattering right- and left-handed electrons off quarks in a deuterium target, researchers have improved, by about a factor of five, on a classic result of mirror-symmetry breaking ...

Quarks don't actually have colors, but they do have charges as governed by the strong interaction. Only with these unique properties can the building blocks of matter combine to produce the ...

Quarks and gluons differ from other elementary particles in that they have a property known as colour charge, which is unrelated to visible colours.

While gluons are responsible for generating most of the visible mass in the universe, their role inside nuclei remains poorly ...

Quarks and antiquarks, which interact with the strong nuclear force, have color charges that... [+] correspond to red, green and blue (for the quarks) and cyan, magenta and yellow (for the ...

Quarks make up all matter, but have never been seen by themselves. And they have “flavors” and “colors” — though neither term has any relevance to what they actually do.

Quarks are found in protons and are bound together by forces which cause all other known forces of nature to fade. To understand the effects of these strong forces between the quarks is one of the ...

Do top quarks, nature's heaviest elementary particle, obey Einstein's rules at all times of day and night? Scientists at the Large Hadron Collider have the answer.

Instead, quarks must be constrained to points on a grid, separated by some fixed distance and connected by the force-carrying gluons. This approach, which discretizes space, is known as lattice QCD.
