Study of $B_s^0\to l^{+}{l}^{-}\gamma$ decays in the nonuniversal Z' model

Abstract

We investigate $B_s^0\to l^{+}{l}^{-}\gamma$ decays in a nonuniversal Z' model derived from extension of the standard model (SM). Considering the Z'-mediated flavor changing neutral current (FCNC) effects we calculate the branching ratio and forwardbackward asymmetry for $B_s^0\to l^{+}{l}^{-}\gamma$ decay processes. We compare the obtained results with predictions of the SM and discuss the sensitivity of the observables to Z' boson coupling parameters. We find the branching ratios are enhanced by one order from SM predictions in Z' model scenario. We also observe the variation of forward-backward asymmetry with the Z' boson coupling parameters portrait discrimination between NP effects and SM results.
