hadron (plural hadrons)

  1. (particle) A composite particle that comprises two or more quarks held together by the strong force and (consequently) can interact with other particles via said force; a meson or a baryon.

      The weak decays of b hadrons are dominated by the spectator model process whereby the b quark decays to a c quark (or occasionally a u quark) with the emission of an external W, while the non-b antiquark or diquark acts simply as a passive spectator to the decay.

      One can use the lattice simulations, which do represent the rigorous consequences of non-perturbative QCD, as guidance for models of hadron structure.

      And hence colour, which was initially an ad hoc concept, later turned out to be an empirically confirmed reality of hadrons.
