  • There they can switch identities time and time again, becoming another quark or an antiquark.

    The Nobel Prize in Physics 2008 - Illustrated Presentation

  • The tracing is of the overall occillation frequency … NOT a profile of overall quark/antiquark occillation behavior.

    Incompatible Arrows, IV: F. Scott Fitzgerald

  • CDF physicists have previously measured the rate of the matter-antimatter transitions for the B_s meson, which consists of the heavy bottom quark bound by the strong nuclear interaction to a strange antiquark.

    Incompatible Arrows, IV: F. Scott Fitzgerald

  • Pions are hadrons, consisting of a quark and an antiquark.

    CDF Ghost Muons

  • The subsample in question came to light in the course of the measurement of the b quark pair production cross section, which is proportional to the rate at which events with a b quark and a b antiquark are produced.

    CDF Ghost Muons

  • Quanta devoid of internal structure (such as quarks, leptons, and intermediate bosons) are the result of interaction with one quantum of space; particles endowed with internal structure (baryons constituted of three quarks and mesons made up of a quark-antiquark pair) are the product of interaction with several QS.


  • It decays, nearly instantly, into the heaviest quark-antiquark or lepton-antilepton pair it can.

    Bump Hunting (Part 1)

  • If you produce a Higgs boson, it will decay to the heaviest quark or lepton paris (for example a bottom quark and antiquark) that it can.

    Higgs 101

  • There are six quarks (and their antiquark mirror images), and six leptons.

    Higgs 101

  • (If you dump in enough energy to pry one out, it'll go into creating a quark-antiquark pair with the new quark taking the place of the old one -- all you've done is create a meson.)

  • A hypothetical, truly fundamental crumb of something that is allegedly cheese, but probably isn't.
