我們研究Bd->(eta,eta')ll,Bs->(eta,eta',phi)ll, 和Bc->D_{s,d}ll 稀有衰變,這些衰變是由味改變中性電流過程 所產生。在我們的分析中,我們用光前沿夸克模型和夸克組成模型計算強子形狀因子。我們期待Bd 和 B_{s,c} 的衰變可以分別在未來的B工廠和強子碰撞器中得到驗證。
We study the exclusive rare decays of Bd->(eta,eta')ll,
Bs->(eta,eta',phi)ll and Bc->D_{sd}ll, arising from the inclusive flavor changing neutral current processes of b->(s,d)ll. In our analysis, we use the hadronic form factors calculated in the light-front and constituent quark models. We find that these rare Bd and B_{s,c} decay modes can be tested in the future B factories and hadronic colliders, respectively.
