| 英文摘要 | The doubly charmed exotic state T-cc recently discovered by the LHCb Collaboration could well be a DD* molecular state long predicted in various theoretical models, in particular, the DD* isoscalar axial vector molecular state predicted in the one-boson-exchange model. In this work, we study the DDD* system in the Gaussian expansion method with the DD* interaction derived from the one-boson-exchange model and constrained by the precise binding energy of 273 +/- 63 keV of T-cc with respect to the D*+D-0 threshold. We show the existence of a DDD* state with a binding energy of a few hundred keV, isospin 1/2, and spin-parity 1(-). Its main decay modes are DDD pi and DDD gamma. The existence of such a state could in principle be confirmed with the upcoming LHC data and will unambiguously determine the nature of the T-cc(+) state and of the many exotic states of similar kind, thus deepening our understanding of the nonperturbative strong interaction. |
