    The idea of colour was introduced by O.W. Greenberg, Phys.Rev.Lett.13, 598 (1964). The idea that the strong interactions might be described by a non-Abelian gauge theory of colour originates in H. Fritzsch and M. Gell-Mann, Proc. XVI Int. Conf. on High Energy Physics (National Accelerator Laboratory, 1972) p.135; H. Fritzsch, M. Gell-Mann, and H. Leutwyler, Phys.Lett. 74B, 365(1973); S. Weinberg, Phys.Rev.Lett.31, 494(1973).Google Scholar

    J. Weinstein and N. Isgur, Phys. Rev. Lett. 48, 659 (1982); Phys. Rev. D27, 588(1983). This interpretation is very close to a suggestion in the context of the bag model by R.L. Jaffe, Phys. Rev. D15, 267,281 (1977); R.L. Jaffe and K. Johnson, Phys. Lett. 60B, 201(1976); R.L. Jaffe, Phys. Rev. D17, 1444(1978).Google Scholar
