Example Sentences

- "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."
