a scheme that explains the quantum numbers of all the baryons and mesons by assuming that baryons are composed of three quarks and mesons of a quark and an antiquark, with different combinations of quark and antiquark flavors giving different sets of quantum numbers.

[kwawrk, kwahrk] /kwɔrk, kwɑrk/ noun 1. Physics. any of the hypothetical particles with spin 1/2, baryon number 1/3, and electric charge 1/3 or −2/3 that, together with their antiparticles, are believed to constitute all the elementary particles classed as baryons and mesons; they are distinguished by their flavors, designated as up (u), down (d), strange […]
noun, Astronomy. 1. a hypothetical celestial object that is intermediate in density between a neutron star and a black hole, possibly the remnant of a massive neutron star with all particles reduced to strange quarks. quark star A superdense celestial object that is formed when the remnants of old stars collapse on themselves, denser than […]
