Quantum Weakdynamics as an SU(3)I Gauge Theory: Grand Unification of Strong and Electroweak Interactions
Abstract
Quantum weakdynamics (QWD) as an SU(3)I gauge theory with the Theta vacuum term is considered to be the unification of the electroweak interaction as an SU(2)L x U(1)Y gauge theory. The grand unification of SU(3)I x SU(3)C beyond the standard model SU(3)C x SU(2)L x U(1)Y is established by the group SU(3)I. The grand unified interactions break down to weak and strong interactions at a new grand unification scale 103 GeV, through dynamical spontaneous symmetry breaking (DSSB); the weak and strong coupling constants are the same, alphai = alphas ~ 0.12, at this scale. DSSB is realized by the condensation of scalar fields, postulated to be spatially longitudinal components of gauge bosons, instead of Higgs particles. Quark and lepton family generation, the Weinberg angle sin2 thetaW = 1/4, and the Cabbibo angle sin thetaC = 1/4 are predicted. The electroweak coupling constants are alphaz = alphai/3, alphaw = alphai/4, alphay = alphai/12, and alphae = alphai/16 = 1/137; there are symmetric isospin interactions.
