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

TL;DR

This paper investigates the effects of a family nonuniversal Z' model on the decay process $B_s -> \gamma l^+ l^-$, focusing on observables like branching ratios and asymmetries, and compares predictions with the Standard Model.

Contribution

It introduces a novel analysis of the $B_s -> \\gamma l^+ l^-$ decay within a family nonuniversal Z' framework, providing new predictions for experimental testing.

Findings

Predicted deviations from the Standard Model in branching ratios.

Altered lepton polarization and forward-backward asymmetries.

Potential signals detectable at LHCb.

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.
