论文摘要
pentaquark状态，$ p_ {c}（4312）$，$ p_ {c}（4440）$和$ p_ {c}（4450）$，可以很好地排列到$ \ bar {d} $ dict y dick y dick y dick y light a} $} $}的$ \ bar {dick} $} $}^c}的七分之一的多重上。旋转对称性，而$ξ_{cc}^{（\ ast）}σ_{c}^{（\ ast）} $系统可以与$ \ bar {d}^{（\ ast）}σ_{c}^{c}^{（\ ast}^{（\ ast} $ SAMPLY ANTENT）在这项工作中，我们采用一个玻色子交换模型来研究$ξ_{cc}^{（\ ast）} $和$σ_{c}^{（\ ast）} $之间的相互作用，并具有pentaquark系统的约束。我们表明，在Isospin-1/2扇区中自然出现了十个三重魅力的Dibaryons的多重，而Isospin-3/2扇区中只有三个。此外，我们研究了他们的夸克风味伙伴。在ISOSPIN-1/2扇区中发现了十个三重底部的二尼巴里子，而Isospin-3/2扇区中只有9个。此外，$ 0^{+} $ $ $ $ $ $之一的预测质量分裂，发现发现其$ 1^{+} $对应合与$ 1^{+} $对应物相一致，这与最近在pan $ et $ et $ $ al $ $ $ al $中指出的重型Antiquark Diquark Symetry所暗示的相关性是一致的。
The pentaquark states, $P_{c}(4312)$, $P_{c}(4440)$ and $P_{c}(4450)$, can be nicely arranged into a multiplet of seven molecules of $\bar{D}^{(\ast)}Σ_{c}^{(\ast)}$ dictated by heavy quark spin symmetry, while the $Ξ_{cc}^{(\ast)}Σ_{c}^{(\ast)}$ system can be related to the $\bar{D}^{(\ast)}Σ_{c}^{(\ast)}$ system via heavy antiquark diquark symmetry. In this work we employ the one boson exchange model to study the interactions between $Ξ_{cc}^{(\ast)}$ and $Σ_{c}^{(\ast)}$ with constraints from the pentaquark system. We show that a multiplet of ten triply charmed dibaryons emerge naturally in the isospin-1/2 sector, while only three appear in the isospin-3/2 sector. In addition, we study their heavy quark flavor partners. Ten triply bottom diybaryons are found in the isospin-1/2 sector, while only nine are likely in the isospin-3/2 sector. Furthermore, the predicted mass splitting between the $0^{+}$ $Ξ_{cc}Σ_{c}$ state and its $1^{+}$ counterpart is found to be consistent with the correlation implied by heavy antiquark diquark symmetry recently pointed out in Pan $et$ $al$..
