hadron  (hdrn)

Any of a class of subatomic particles composed of a combination of two or more quarks or antiquarks. Quarks (and antiquarks) of different colors are held together in hadrons by the strong nuclear force. Hadrons include both baryons (composed of three quarks or three antiquarks) and mesons (composed of a quark and an antiquark). The combination of quark colors in a hadron must be neutral, for example, red and antired (as in a pion) or red, blue, and green (as in a proton). Compare baryonlepton

hadron - any elementary particle that interacts strongly with other particles antibaryon - the antiparticle of a baryon; a hadron with a baryon number of -1 antimeson - the antiparticle of a meson antiquark - the antiparticle of a quark baryon, heavy particle - any of the elementary particles having a mass equal to or greater than that of a proton and that participate in strong interactions; a hadron with a baryon number of +1 elementary particle, fundamental particle - (physics) a particle that is less complex than an atom; regarded as constituents of all matter meson, mesotron - an elementary particle responsible for the forces in the atomic nucleus; a hadron with a baryon number of 0 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"
