Lepton flavour violating ${\Lambda }_b$ decays in non-universal Z${}^{\prime }$ model

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${}^{\prime }$ 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 forward-backward asymmetry in new physics (NP). The predicted values of the observables are very interesting and that might emboss the footprints of NP more aesthetically.
