摘要：
Motivated by the recent LHCb results of lepton flavour violation on b -> s and b -> c transitions we study the lepton flavour violating (LFV) baryonic decays Lambda(b) -> Lambda l(i)(+) l(j)(-) in non-universal Z' model. We discuss the two-fold decay distribution of Lambda(b) -> Lambda l(i)(+) l(j)(-) decays in terms of transversity amplitudes. From this distribution we study the differential branching ratio and lepton side forwardbackward asymmetry in new physics (NP). The predicted values of the observables are very interesting and that might emboss the footprints of NP more aesthetically.
