论文摘要
我们提出了一种$ω_c\ toπ^+ω(2012)$生产的机制,该机制通过外部排放cabibbo偏爱弱衰减模式,其中$ω(2012)$是通过$ \ bar {k} at enportaction of $ \ bar {k}ξ^*(1530)$,$ \ bar $ \ bar {k} e eay decay decay decay deceay的$ \ bar {k}ξ^*(1530)$的交互作用。 $ω(2012)$在这张图片中以$ \ bar {k}ξ$衰减,结果与Belle数据兼容。结果,图片可以评估直接衰减$ω_c^0 \ toπ^+k^ - ξ^0 $和衰减$ω_c^0 \toπ^+\ bar {k}ξ^*$,$π^+precpling coupling的$ \ bar bar {我们表明,在不确定性并使用最近的Belle测量数据中,所有这三个通道约为(12-20)\%的总$ω_c\toπ^+K^ - ξ^0 $衰减率。分子图与所有数据的一致性是通过证明$ω_c\ to to t to bar {k}^{* 0} \ to $ω_c\ to $ω_c\ toπ^+ω^+toπ^+k^+k^+k^ - ξ^0 $的$ 85 $的$ 85 $的$ 85 $ com π^+k^ - ξ^0 $。
We present a mechanism for $Ω_c \to π^+ Ω(2012)$ production through an external emission Cabibbo favored weak decay mode, where the $Ω(2012)$ is dynamically generated from the interaction of $\bar{K}Ξ^*(1530)$, $ηΩ$, with $\bar{K}Ξ$ as the main decay channel. The $Ω(2012)$ decays later to $\bar{K}Ξ$ in this picture, with results compatible with Belle data. The picture has as a consequence that one can evaluate the direct decay $Ω_c^0 \to π^+K^- Ξ^0$ and the decay $Ω_c^0 \to π^+\bar{K} Ξ^*$, $π^+ηΩ$ with direct coupling of $\bar{K}Ξ^*$ and $ηΩ$ to $K^- Ξ^0$. We show that, within uncertainties and using data from a recent Belle measurement, all these three channels account for about (12-20)\% of the total $Ω_c \to π^+K^- Ξ^0$ decay rate. The consistency of the molecular picture with all the data is established by showing that $Ω_c \to Ξ^0 \bar{K}^{*0} \to Ξ^0K^- π^+$ together with $Ω_c \to π^+ Ω^* \to π^+K^- Ξ^0 $ account for about 85\% of the total $Ω_c \to π^+K^- Ξ^0 $.
