Abstract

Lepton flavour violation (LFV) is one of the most trending topics to probe new physics (NP). The powerful accelerators have enhanced their intensities to observe the LFV decays very precisely. In this situation, the theorists are also interested to study these decays in various NP models and in model independent way to get precise results. Motivated by these results we have studied B decays into K2^star(1430)l1 l2 in non-universal Z^' model. Here, we have structured the two-fold angular distribution of the decays in terms of transversity amplitudes and the transversity amplitudes are formed with NP Wilson coefficients. The variation of the branching ratios and forward backward asymmetries show the sensitivity of NP. The observables calculated in this work are very interesting and might provide a new way towards NP.
