Abstract：
We investigate the rare baryonic λ_b→λl⁺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 λ_b→λl⁺l^- decays. We find significant deviations from their SM predictions, which could indicate new physics arising from the Z' gauge boson.
- Z'boson ,
- baryonic decays ,
- flavour-changing neutral currents ,
- heavy quark effective theory ,
- models beyond the standard model
