摘要
We investigate collider signals for gauged flavor symmetries that have been proposed in models of dynamical electroweak symmetry breaking and fermion mass generation. We consider the limits on the masses of the gauge bosons in these models which can be extracted from Fermilab Tevatron run I data in dijet production. Estimates of the run II search potential are provided. We show that the models also give rise to significant signals in single top quark production which may be visible at run II. In particular we study chiral quark family symmetry and SU(9) chiral flavor symmetry. The run I limits on the gauge bosons in these models lie between 1.5 and 2 TeV and should increase to about 3 TeV in run Il. Finally, we show that an SU(12) enlargement of the SU(9) model, including leptonic interactions, is constrained by low energy atomic parity violation experiments to lie outside the reach of the Tevatron.
