dc.descriptionWe discuss a model in which the third generation fermions undergo a different $SU(2)$ weak interaction from the first two generation fermions. In general, a flavor changing neutral current interaction is expected. Constrained by the precision low energy data, the mass ($M_{Z'}=M_{W'}$) of the heavy gauge bosons is bounded from below to be about $1.1$ TeV for $α_s=0.125$ and about $1.3$ TeV for $α_s=0.115$, at the $3σ$ level. This model favors a larger $R_b$ and a smaller $R_c$ as compared with the Standard Model, but it does not explain the $R_c$ data. If one takes the $R_b$ data seriously, then $M_{Z'}$ is bounded, at the $3σ$ level, to be $462$ GeV $< M_{Z^{\prime}} \cosϕ< 1481\,\, {\rm{GeV}}$, where $\cosϕ$ is the mixing angle between the two $SU(2)$'s in the model. Effects predicted for high energy experiments at the Tevatron, LEP140, LEP-II, LHC, and future linear colliders are also discussed.
