摘要We study a simple ultraviolet complete and anomaly-free Z' model based on a U(1)' gauge family symmetry without introducing extra fermions beyond the standard model. The U(1) ' group is diagonal in the three-family space in which the U(1)' charges of the first and second families are the same but different from those of the third family. After spontaneous symmetry breaking and rotating to the mass eigenstates of quarks and leptons, there exist, in general, both flavor-conserving and flavor-changing couplings. In the flavor-conserving case, we use the latest dijet and dilepton search at the LHC to constrain the mass and gauge couplings of Z'. Also we show that in the flavor-changing and left-right asymmetry case, the t-channel Z' process can only contribute to part of the forward-backward asymmetry in the top quark pair production observed at the Tevatron by taking into account the constraint from the same sign top production at the LHC.
