Semileptonic Transition of $Σ_b \rar Σμ^+ μ^-$ in Family Non-universal $Z^{\prime }$ Model

Abstract

Using newly available form factors obtained from light cone QCD sum rules in full theory, we study the flavor changing neutral current transition of $Σ_b \rar Σμ^+ μ^-$ decay in the family non-universal $Z^{\prime }$ model. In particular, we evaluate the differential branching ratio, forward-backward asymmetry as well as some related asymmetry parameters and polarizations. We compare the obtained results with the predictions of the standard model and discuss the sensitivity of the observables under consideration to family non-universal $Z^{\prime }$ gauge boson. The order of differential branching ratio shows that this decay mode can be checked at LHC in near future.
