Abstract

Using experimental results at the Z-pole and atomic parity violation, we perform a χ2 fit at 95% C.L. to obtain family-dependent bounds to Z2 mass and ZμZμ mixing angle θ in the framework of SU(3)cSU(3)LU(1)X models. The allowed regions depend on the assignment of the quark families in mass eigenstates into the three different families in weak eigenstates that cancel anomalies.
