| Abstract: | In unified gauge theories with massive “color” gluons, the physical requirement of maintaining “color” SU(3) as a global classification symmetry is shown to lead to the following restrictions: (i) the local unifying symmetry group must be of the form Gflavor?Gcolor; (ii) quarks are to be integer charged; (iii) the number of flavors is an integral multiple of the number of “colors”. |
