Can quarks have integer charge

We construct a conservative model of quarks and gluons with the Han-Nambu charge assignment by slightly breaking the SU(3)/sub color/ x U(1) gauge symmetry observed at present energies. At very large masses, stable integrally charged colored quark states appear. The model is conservative in the sense that it differs as little as possible from conventional quark-gluon models at low energies. In particular, all conventional tests proposed to discriminate between fractional and integer quark charges fail. However, the model requires light charged Higgs scalars which should have been seen in e/sup +/e/sup -/..-->.. hadrons at present energies.
