论文摘要
$ d^{\ ast} $介子的当前知识仍然不足。受到高亮度和高精度实验的积极发展前景的鼓舞，Cabibbo最喜欢的非leptonic $ d^{\ ast} $ $ {\ to} $ $ \ bar {k} wist {k}π^{+} $ \ bar {k}ρ{+} $弱衰减是通过幼稚的分解方法研究的。发现这些过程的分支比率最高可达$ {\ cal o}（10^{ - 10}）$或更多，并且可以在将来在STCF，CEPC，FCC-EE和LHCB@HL-LHC实验中访问。甚至可以搜索$ d^{{\ ast} 0} $ $ {\ to} $ $ k^{{\ ast} - }π^{+} $和$ k^{ - } - }ρ^{+} $在运行的SuperKekB Blastements上衰减。
The current knowledge on the $D^{\ast}$ mesons are still inadequate. Encouraged by the positive development prospects of high-luminosity and high-precision experiments, the Cabibbo-favored nonleptonic $D^{\ast}$ ${\to}$ $\bar{K}π^{+}$, $\bar{K}^{\ast}π^{+}$, $\bar{K}ρ^{+}$ weak decays are studied with the naive factorization approach. It is found that branching ratios of these processes can reach up to ${\cal O}(10^{-10})$ or more, and can be accessible at STCF, CEPC, FCC-ee and LHCb@HL-LHC experiments in the future. It might even be possible to search for the $D^{{\ast}0}$ ${\to}$ $K^{{\ast}-}π^{+}$ and $K^{-}ρ^{+}$ decays at the running SuperKEKB experiments.
