论文摘要
在这项工作中，我们在$ e^+e^ - $ collisions中找到了一般三体开放式过程的关键能量诱导的增强（CEE）机制，该过程利用了涉及三体最终州的$ e^+e^ - $ nihihihitation过程的特殊运动行为。我们对三体过程$ e^+e^ - \ to bc \ to b（c \ to de）$进行了一般分析。当$ e^+e^ - $碰撞的质量中心（cm）能量满足$ \ sqrt {s} = m_b+m_c $的关键关系时，显然存在中间$ c $ c $ c $ c $ c $ c $ c $ c $ y y y y y y y iS} $} $或$ m_或$ m_ _ _} $ m_ c $ coble的反射峰。在临界能量上引起的反射增强现象意味着可以在实验上映射新的炭状结构群。以$ e^+e^ - \的示例为d_s^{* - } d_ {s2}^*（2573）^+\ to d_s^{* - }（d^0k^+）$，我们在$ \ sqrt {s} = 4.680 $ gev时进一步说明此新颖现象。更重要的是，建议一系列最佳的CM能量点在三体开放式过程中从$ e^+e^ - $ nihilation中搜索新的charmoniumlium样结构，可以在Besiii和Belleii作为一个新的研究主题，在Besiii和其他Belleii中可以访问。
In this work, we find a Critical Energy induced Enhancement (CEE) mechanism for the general three-body open-charm process at the $e^+e^-$ collisions, which utilizes the peculiar kinematic behavior of the $e^+e^-$ annihilation process involving three-body final states. We present a general analysis of a three-body process $e^+e^-\to BC\to B(C\to DE)$. When the center-of-mass (CM) energy of the $e^+e^-$ collision satisfies a critical relation $\sqrt{s}=m_B+m_C$, there clearly exists the reflection peak of an intermediate $C$ state near the threshold of the invariant mass distribution of $m_{BE}$ or $m_{BD}$, whose formation is very sensitive to the CM energy. The reflection enhancement phenomenon induced at the critical energy means that a new cluster of charmoniumlike structures can be experimentally mapped. Taking an example of $e^+e^-\to D_s^{*-}D_{s2}^*(2573)^+ \to D_s^{*-}(D^0K^+)$, we further illustrate this novel phenomenon when $\sqrt{s}=4.680$ GeV. What is more important is that a series of optimal CM energy points to search for new charmoniumlike structures in three-body open-charm processes from $e^+e^-$ annihilation are suggested, which can be accessible at BESIII and further BelleII as a new research topic.
