Imprints of new physics in {\Lambda}_b decays into {\Lambda}*(1520)l^+ l^- in non-universal Z^' model

Inspired by various updated tantalizing results of LHCb on baryonic sector we study the {\Lambda}_b decays into {\Lambda}^* (1520)l^+ l^- decay in non-universal Z^' model. We present the four-fold angular distributions of the decay in terms of transversity amplitudes. We structure the observables: differential branching ratio, lepton side forward backward asymmetries and polarization fractions in terms of the transversity amplitudes and incorporate the new physics (NP) terms in it. We reduce the number of the form factors using the improved Isgur-Wise relations. We study the observables in the standard model (SM) as well as in non-universal Z^' model. The predicted values are very interesting for the high energy physics community and results might provide prominent footprints of NP.
