论文摘要
$ ddk $ 3体系统的限制是由于$ d $ eNON与ISOSPIN零频道中的$ k $ Meson之间的强烈吸引人的相互作用。此3体绑定状态的最小夸克内容为$ cc \ bar {q} \ bar {s} $,带有$ q = u,d $。一旦发现,这将是一个明显的异国tetraquark州。为了确认$ DDK $系统的现象学研究,我们可以将晶格QCD称为与实验测量平行的强大理论工具。在本文中,通过非相关的有效理论和有限体积的粒子二聚体图片得出了三体量化条件方案。在现有模型输入中计算此三体系统的晶格光谱。这些频谱显示了$ DDK $系统的各种有趣属性,它可能会揭示$ d^*(2317)$的性质。预计将在未来的晶格模拟中测试该谓词光谱。
The $DDK$ 3-body system is supposed to be bound due to the strongly attractive interaction between the $D$ meson and the $K$ meson in the isospin zero channel. The minimum quark content of this 3-body bound state is $cc\bar{q}\bar{s}$ with $q=u,d$. It will be an explicitly exotic tetraquark state once discovered. In order to confirm the phenomenological study of the $DDK$ system, we can refer to lattice QCD as a powerful theoretical tool parallel to the experiment measurement. In this paper, a 3-body quantization condition scheme is derived via the non-relativistic effective theory and the particle-dimer picture in finite volume. Lattice spectrum of this 3-body system is calculated within the existing model inputs. The spectrum shows various interesting properties of the $DDK$ system, and it may reveal the nature of the $D^*(2317)$. This predicated spectrum is expected to be tested in future lattice simulations.
