论文摘要
在核物理学中，特里顿和氦-3核可以理解为三体腺子分子。类似于Triton和氦-3核的松散结合结构，无论是否存在三个Hadron形成的结合状态，这给我们留下了一个空旷的问题。基于单玻色子交换模型以及采用变分方法，我们对三个相同的baryons $ nnn $，$λλ$，$λλ$，$ξξ$和$σσς$的Tritonlike系统进行了全面调查。我们预测，只要它们的两体子系统具有绑定状态，三个相同的Baryon八位基体系统系统的三体分子状态就可能存在。这项工作的数值结果可能有助于对未来三麦分子的理论和实验研究。
In nuclear physics, triton and helium-3 nucleus can be understood as three-body hadronic molecules. Analogous to the loosely bound structures for the triton and helium-3 nucleus, whether there is a bound state formed by three hadrons leaves us an open issue. Based on the one-boson exchange model as well as the adoption of the variational approach, we make a comprehensive investigation on the tritonlike systems of three identical baryons $NNN$, $ΛΛΛ$, $ΞΞΞ$ and $ΣΣΣ$. We predict that the three-body molecular states for the systems of three identical hadrons of baryon octet are probably existent as long as their two-body subsystems have bound states. The numerical results of this work may be helpful for the theoretical and experimental researches on the tri-hadron molecules in future.
