  QCD
       n : a theory of strong interactions between elementary particles
           (including the interaction that binds protons and
           neutrons in the nucleus); it assumes that strongly
           interacting particles (hadrons) are made of quarks and
           that gluons bind the quarks together [syn: {quantum
           chromodynamics}]
