摘要：
The precise prediction of the branching ratios of the very rare decays B (s) (0) -> aEuro,e (+) e (-) and B (d) (0) -> aEuro parts per thousand e (+) e (-) is an important ingredient for high energy research beyond standard model (SM). Recently, the CDF collaboration has reported upper limits for the branching ratios B ( B (s) (0) -> aEuro parts per thousand e (+) e (-) ) < 2.8 x 10(-aEuro parts per thousand 7) and B ( B (d) (0) -> aEuro parts per thousand e (+) e (-) )aEuro,< aEuro,8.3 xaEuro,10(-aEuro parts per thousand 8) at 90 % confidence level. These branching ratios are approximately seven orders of magnitude larger than the SM predictions, providing in this way a direction in which the SM could be extended. In this paper, the B (s) (0) -> aEuro,e (+) e (-) and B (d) (0) -> aEuro parts per thousand e (+) e (-) rare decays in flavor-changing Z' model are studied. Our estimated branching ratios are enhanced from their SM values and provide signals for new physics.
