Lepton flavour violating {Lambda }_{{b}} decays in non-universal {Z}^{prime } model

Abstract

Motivated by the recent LHCb results of lepton flavour violation on brightarrow s and brightarrow c transitions we study the lepton flavour violating (LFV) baryonic decays {Lambda }_{b}rightarrow {Lambda }l_{i}^{+}l_{j}^{-} in non-universal Z^{prime } model. We discuss the two-fold decay distribution of {Lambda }_{b}rightarrow {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.
