Family nonuniversal Z-prime and b to s Gamma decay

Abstract

We have calculated the branching ratio and CP asymmetry of B-->X_s +gamma decay within the family--nonuniversal Z' models. We have established certain bounds on the model parameters using the present experimental bounds. We also comment on the role of family--nonuniversality in the hadronic decay modes of the B meson.
