摘要

We analyze different decay observables of semileptonic decays Bc →(D(*) s,d)μ+ μ-,such as the branching ratio,forward-backward asymmetry,polarization fraction,and lepton polarization asymmetry in the non-universal Z'model.We further study the dependence of the branching fraction to the new model parameters and find that the values of different decay parameters increase in the Z'model,which indicates a possible approach for the search of new physics as well as for the unknown phenomena of the charm B meson.
