Abstract

We investigate the rare baryonic $I^_{b} \to I^ l^{+} l^{-}$ decays in a non-universal $Z^{'}$ model, which is one of the well-motivated extensions of the standard model (SM). Considering the effects of $Z^{'}$ -mediated flavour-changing neutral currents (FCNCs) we analyse the differential decay rate, forward-backward asymmetries and lepton polarisation asymmetries for the $I^_{b} \to I^ l^{+} l^{-}$ decays. We find significant deviations from their SM predictions, which could indicate new physics arising from the $Z^{'}$ gauge boson.
