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