Lepton Asymmetries for the $B_s->\gamma l^{+}{l}^{-}$ Decay in a Family Nonuniversal Z' Model

Abstract

The exclusive $B_s->\gamma l^{+}{l}^{-}$ decay is analyzed in the framework of a family nonuniversal Z' model by calculating the differential branching ratio, double lepton polarizations and forward-backward asymmetries. Our results are compared against those of the Standard Model. The predictions of this work are hoped to can be tested in the near future at LHCb.
