Model based on gauge symmetry groupG=Gwk×[SU(3)×SU(3)]c

We formulate a gauge model for basic interactions based on the symmetry group G = G/sub wk/ x G/sub c/, where G/sub c/ is the chiral symmetry group (SU(3) x SU(3))/sub c/ in color space. G/sub wk/ is taken to be the left-right-symmetric model SU/sub L/(2) x SU/sub R/(2) x U(1). The chiral color symmetry is spontaneously broken in such a way that quarks acquire a common mass and an octet of axial-vector gluons become massive but an octet of vector gluons remain massless. In this way quark mass arises from spontaneous color-chiral-symmetry breaking. The experimental consequences of the left-right-symmetric model are discussed and it is shown that one version of this model gives results similar to the Salam-Weinberg model for the currently available energies. There is also another version, where the results are again similar to the Salam-Weinberg model except that the y dependence for the asymmetry parameter for the deep-inelastic scattering of polarized electrons is completely different although its value at y = 0.21 is compatible with experiment.
