摘要：

Recently, the first evidence for the decay B (s) (0) -> mu (+) mu (-) has been announced by the LHCb Collaboration and the measured branching ratio B( (s) (0) -> mu (+)) = (3.2 (-1.2) (+1.5) ) x 10(-9) is in good agreement with the standard model (SM) expectation. It has also reported an upper limit for B(B (d) (0) -> mu (+) mu (-)) < 9.4 x 10(-10) at 95% confidence level. In this paper, we study the B (s) (0) -> mu (+) mu (-) and B (d) (0) -> mu (+) mu (-) rare decays in flavor-changing Z' model. Our estimated branching ratios are enhanced from their SM values and provide signals for new physics.
