名詞

gluon (plural gluons)

1. (physics) A massless gauge boson that binds quarks together to form baryons, mesons and other hadrons and is associated with the strong nuclear force.
   • 1992 November, George Zebrowski, Marvin Mattelson, “The Enigma of Distance”, in Omni, volume 15, number 2, page 80:

     Naive realism might ask today: Tell me what space is in itself, not in terms of other things. Tell me what a gluon is at bottom, or a neutrino, or a charge.

   • 1995 September, Robert Jaffe, “Where Does the Proton Really Get Its Spin?”, in Physics Today, volume 48, number 9, →DOI, page 24:

     The so-called spin crisis has had important effects beyond simply confronting theorists with a particularly sharp challenge to their incomplete understanding of quantum chromodynamics, the underlying field theory of quarks and the gluons that mediate their strong interactions.

   • 2004 September 7, Peter Weiss, “Starting from Square One”, in Science News, volume 166, number 6, →DOI, pages 90–1:

     Lattice QCD explores the particle realm by taking a different tack. It simulates quark and gluon behaviors by applying the full QCD theory to a tiny grid like facsimile of the space-time in which particles actually interact.
