摘要:

用微扰QCD方法研究了$Υ(nS)$ ${\to}$ $B_{c}^{\ast}D$弱衰变($n$ $=$ $1$,$2$,$3$).发现CKM偏爱的$Υ(nS)$ ${\to}$ $B_{c}^{\ast}D_{s}$衰变的分支比为${\cal O}(10^{-10})$,这可能是未来LHC和SuperKEKB实验的潜在目标.

英文摘要:

The $Υ(nS)$ ${\to}$ $B_{c}^{\ast}D$ weak decays ($n$ $=$ $1$, $2$, $3$) are investigated with perturbative QCD approach. It is found that the CKM-favored $Υ(nS)$ ${\to}$ $B_{c}^{\ast}D_{s}$ decays have branching ratio of ${\cal O}(10^{-10})$, which might be potentially accessible to the future LHC and SuperKEKB experiments.
