quark

Noun
  1. (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 (synset 109424709)
    "quarks have not been observed directly but theoretical predictions based on their existence have been confirmed experimentally"
    referred to in: natural philosophy, physics - the science of matter and energy and their interactions
    is a type of: elementary particle, fundamental particle - (physics) a particle that is less complex than an atom; regarded as constituents of all matter
    subtypes:
    • beauty quark, bottom quark - a quark with a charge of -1/3 and a mass about 10,000 times that of an electron
    • charm quark - 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 - a stable quark with an electric charge of -1/3 and a mass 607 times that of an electron
    • squark, strange quark - a quark with an electric charge of -1/3 and a mass 988 times that of an electron and a strangeness of -1
    • top quark, truth quark - a hypothetical quark with a charge of +2/3 and a mass more than 100,000 times that of an electron
    • up quark - a stable quark with an electric charge of +2/3 and a mass 607 times that of an electron
    is a part of: hadron - any elementary particle that interacts strongly with other particles
  2. Fresh unripened cheese of a smooth texture made from pasteurized milk, a starter, and rennet (synset 107870431)
    is a type of: cheese - a solid food prepared from the pressed curd of milk
    same as: quark cheese
