Related to hadronic: quark


Any of a class of subatomic particles that are composed of two or three quarks and participate in strong interactions. The class of hadrons is divided into the mesons and baryons.

quark - (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; "quarks have not been observed directly but theoretical predictions based on their existence have been confirmed experimentally"
