论文摘要
最近的晶格QCD计算表明，可能存在类似于具有较小绑定能量的Deuteron的$ d_ {nΩ} $ dibaryon状态。在这项工作中，我们提出了一种语音分子方法来研究这种外来状态的动力学特性。我们使用一种现象学的拉格朗日方法来描述$ d_ {nΩ} $状态与其组成部分的耦合，并将其衰减到传统的哈子中，$ d_ {nΩ} \toλξ$和$ d_ {nΩ}} \ to c $σξ$。衰减速率总和的预测在数百keV范围内。此外，我们发现$ d_ {nΩ} \至λξ$模式是主导的，最好在未来的RHIC实验中搜索。
Recent lattice QCD calculations showed that a $d_{NΩ}$ dibaryon state similar to the deuteron with small binding energy may exist. In this work we propose a hadronic molecular approach to study the dynamical properties of this exotic state. We use a phenomenological Lagrangian approach to describe the coupling of the $d_{NΩ}$ state to its constituents and the decays into conventional hadrons, $d_{NΩ} \to ΛΞ$ and $d_{NΩ} \to ΣΞ$. Predictions for the sum of the decay rates are in the range of a few hundred keV. In addition, we find that the $d_{NΩ} \to ΛΞ$ mode is dominant, preferably searched for in a future RHIC experiment.
