Examples

“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.”
