摘要Motivated by flavor non-universality and anomalies in semi-leptonic B-meson decays, we present a general and systematic discussion about how to construct anomaly-free U(1)' gauge theories based on an extended standard model with only three right-handed neutrinos. If all standard model fermions are vector-like under this new gauge symmetry, the most general family non-universal charge assignments, (a, b, c) for three-generation quarks and (d, e, f) for leptons, need satisfy just one condition to be anomaly-free, 3(a+b+c)=-(d+e+f). Any assignment can be linear combinations of five independent anomaly-free solutions. We also illustrate how such models can generally lead to flavor-changing interactions and easily resolve the anomalies in B-meson decays. Probes with B-s-(B) over bar (s), mixing, decay into tau(+/-), dilepton and dijet searches at colliders are also discussed.
