Abstract

We construct a class of anomaly-free supersymmetric U(1)′ models that are characterized by family nonuniversal U(1)′ charges motivated from E6 embeddings. The family nonuniversality arises from an interchange of the standard roles of the two SU(5) 5* representations within the 27 of E6 for the third generation. We analyze U(1)′ and electroweak symmetry breaking and present the particle mass spectrum. The models, which include additional Higgs multiplets and exotic quarks at the TeV scale, result in specific patterns of flavor-changing neutral currents in the b→s transitions that can accommodate the presently observed deviations in this sector from the standard model predictions.
