Lepton flavour violating Λb decays in non-universal Z′ 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' 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.

Automated summary

Motivated by recent LHCb results, we studied lepton flavour violating baryonic decays in non-universal Z' model. The two-fold decay distribution and related properties such as differential branching ratio and lepton side forwardbackward asymmetry were analyzed, predicting interesting observable values potentially reflecting new physics footprints more aesthetically.
