So long, and thanks for all the quarks As an announcement is made in Europe that may shake physics to its foundations, America’s largest particle accelerator is to be switched off ...

All stable configurations of quarks, antiquarks, and gluons have zero net color, which requires either three quarks (because red + blue + green sum to colorless), three antiquarks ...

Just kick all your quarks into Delta resonance. But all forms of resonance add mass. Simply put, the position of the quarks, and the forces acting on them, are part of the mass of the nucleon.

Physicists at the ATLAS detector of the Large Hadron Collider (LHC) have spotted top quarks — the heaviest of all known elementary particles — that were produced by the collision of atomic ...

In total, six quarks are enough to explain all hadrons found so far: up, down, charm, strange, bottom, top. For example, a proton is made of two up quarks and a down quark.

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

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 ...

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.

Note: For a definition of unfamiliar terms, see our glossary. The fundamental particles of the universe that physicists have identified—electrons, neutrinos, quarks, and so on—are the "letters ...

With every discovery in this field of particle physics in the past 50 years, however, more questions arise about how quarks influence the universe's growth and ultimate fate. Here are seven ...

Are there pea-sized objects as heavy as the Moon out there in space? Perhaps so, if quarks, the constituent particles of atoms, are themselves made up of still smaller particles. Fredrik Sandin ...

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.
