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

Abstract

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 $D{D}^{\ast }$ 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 $D{D}^{\ast }$ 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.
