$T^+_{cc}$及其美丽伙伴的强子分子解释

Hadronic molecule interpretation of $T^+_{cc}$ and its beauty-partners

Huimin Ren, Fan Wu, Ruilin Zhu

摘要:

受LHCb合作组发现的一种新的四夸克态$T_{cc}^+$的启发,我们研究了$T_{cc}^+$的$DD^*$强子分子解释.通过计算,这种新结构$T_{cc}^+$的质量和衰变宽度可以用单介子交换势模型来理解。这些$DD^*$强子分子与$J^P=1^+$的结合能在$1MeV$附近。此外,我们还研究了强子分子$T^+_{cc}$的可能的美丽伴侣$T_{bb}(10598)$,这在未来的LHCb实验中可能是可行的。

英文摘要:

Motivated by the latest discovery of a new tetraquark $T_{cc}^+$ with two charm quarks and two light antiquarks by LHCb Collaboration, we investigated the $DD^*$ hadronic molecule interpretation of $T_{cc}^+$. By calculation, the mass and the decay width of this new structure $T_{cc}^+$ can be understood in one-meson exchange potential model. The binding energies for these $DD^*$ hadronic molecules with $J^P=1^+$ are around $1MeV$. Besides, we also studied the possible beauty-partners $T_{bb}(10598)$ of hadronic molecule $T^+_{cc}$, which may be feasible in future LHCb experiments.
