摘要：

We study the effect of non-universal Z' boson on the rare leponic decay modes of B-s* mesons, mediated by b -> sll quark transition. Rare B decays are sensitive to various new physics operators. As B mesons are composite particles, such decay modes of the excited states are ideal for probing new physics beyond the standard model. We have constrained our model parameters from B-s,B-d-(B) over bar (s,d) mixing data to predict the lepton polarization asymmetry of B-s,B-d*->mu(+)mu(-) channel. It is found that this asymmetry deviates from its SM prediction along with the Z' effect.
