| antiquark | (n) the antiparticle of a quark |
| bottom quark | (n) a quark with a charge of -1/3 and a mass about 10, 000 times that of an electron, Syn. beauty quark |
| charm quark | (n) a quark with an electric charge of +2/3 and a mass 2900 times that of an electron and a charm of +1 |
| down quark | (n) a stable quark with an electric charge of -1/3 and a mass 607 times that of an electron |
| quark | (n) (physics) hypothetical truly fundamental particle in mesons and baryons; there are supposed to be six flavors of quarks (and their antiquarks), which come in pairs; each has an electric charge of +2/3 or -1/3, Example: quarks have not been observed directly but theoretical predictions based on their existence have been confirmed experimentally |
| quark cheese | (n) fresh unripened cheese of a smooth texture made from pasteurized milk, a starter, and rennet, Syn. quark |
| strange quark | (n) a quark with an electric charge of -1/3 and a mass 988 times that of an electron and a strangeness of -1, Syn. squark |
| top quark | (n) a hypothetical quark with a charge of +2/3 and a mass more than 100, 000 times that of an electron, Syn. truth quark |
| up quark | (n) a stable quark with an electric charge of +2/3 and a mass 607 times that of an electron |
