Hadronic Molecule Interpretation of Tcc+ and Its Beauty Partners

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 1 MeV. Besides, we also studied the possible beauty partners T-bb(10598) of hadronic molecule T-cc(+), which may be feasible in future LHCb experiments.
