Analysis of λbλ l+l- rare decays in a non-universal Z' model

Abstract: We investigate the rare baryonic λbλl+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 λbλl+l- decays. We find significant deviations from their SM predictions, which could indicate new physics arising from the Z' gauge boson.
