Q q

  • quantum chromodynamics

    a quantum field theory that describes quarks and gluons and their interactions, with the color of the quarks playing a role analogous to that of electric charge. Abbreviation: QCD. Also called chromodynamics. Compare color (def 18).

  • asymptotic freedom

    a property of the force between quarks, according to quantum chromodynamics, such that they behave almost like free particles when they are close together within a hadron.

  • baryon number

    the number of baryons in a system minus the number of antibaryons

  • bottom quark

    a type of quark with a mass of c. 4.7 to 5.3 GeV/c2, a negative charge that is 1⁄3 the charge of an electron, zero charm, and zero strangeness

  • charmed quark

    a type of quark with a mass of c. 1.0 to 1.6 GeV/c2, a positive charge that is 2⁄3 the charge of an electron, +1 charm, and zero strangeness

  • gluon

    an unobserved massless particle with spin 1 that is believed to transmit the strong force between quarks, binding them together into baryons and mesons.
