Abstract：
We study the pure leptonic decays B_s,d→μ⁺μ^－ in a Flavor Changing Z′ Model. From the recent measurements of the branching ratios B(B_s,d→μ⁺μ^－), we have derived the bounds on the effective μ-μ-Z′ lepton coupling B_μμ^L. We find that, (i) if neglecting the contribution from the right-handed lepton coupling B_μμ^R, we obtain 1.32< B_μμ^L <3.32; (ii) if considering the contribution from the right-handed lepton coupling B_μμ^R and setting B_μμ^L=B_μμ^R, we obtain 0.99< B_μμ^L<2.19. Our results could be useful for researching Z′ effects.
