quark meaning

• Noun: quark  kwork or kwaa(r)k
  1. (physics) hypothetical truly fundamental particle in mesons and baryons; there are supposed to be six flavours of quarks (and their antiquarks), which come in pairs; each has an electric charge of +2/3 or -1/3
     "quarks have not been observed directly but theoretical predictions based on their existence have been confirmed experimentally" 
  2. Fresh unripened cheese of a smooth texture made from pasteurized milk, a starter, and rennet
     - quark cheese, curd cheese [Brit]

  Derived forms: quarks

  Type of: cheese, elementary particle, fundamental particle

Examples

1. using this identification, we read off the quantum numbers of the quarks.
2. perhaps partons or quarks will be found with this accelerator.
3. superpotent atom smashers will undertake the quark quest in the 1980s.
4. the different kinds of quarks or leptons are known technically as flavors.
5. we shall see later that gluons are essential to the dynamics of the quarks inside the proton.
