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, down, strange, charm, bottom or beauty, and top or truth, and their colors, red, green, and blue.Compare color, flavor, quantum chromodynamics, quark model.

In this process, the quark turns into an anti-quark and the anti-quark turns into a quark.
This unique trait has led scientists to believe that some extreme physics might take place in their innards — perhaps even the dissolution of neutrons themselves into a softer goo known as quark matter.
For example, if quarks are free agents within the most massive neutron stars, the immense pressure will compress the neutron star’s core more than if quarks remain within neutrons.
For example, particles known as quarks — usually contained within protons and neutrons — may roam freely in a neutron star’s center.
Mashed together in different combinations, quarks make up a variety of larger particles, including protons and neutrons.
Jemmy Quark left him, and, rushing to the town, cried out that something horrible had washed ashore.
There was now a sublime scorn printed on the features of Jemmy Quark.
