The investigation using the one-boson exchange model suggests that specific S-wave charmed meson states with certain I(JP) values are promising candidates for doubly charmed molecular tetraquark states. With the accumulation of experimental data at Run III and a High-Luminosity LHC upgrade, these predicted states could potentially be observed at LHCb in the near future.
Stimulated by the newly reported doubly charmed tetraquark state T+cc by LHCb, we carry out a systematic investigation of the S-wave interactions between the charmed meson (D, D*) in H-doublets and the charmed meson (D1, D*2) in T-doublets by adopting the one-boson exchange model. Both the S-D wave mixing effect and the coupled channel effect are taken into account. By performing a quantitative calculation, we suggest that the S-wave D*D1 states with I(JP) = 0(0-, 1-) and the S-wave D*D*2 states with I(JP) = 0(1-, 2-) should be viewed as the most promising candidates of the doubly charmed molecular tetraquark states, and the S-wave DD1 state with I(JP) = 0(1-) and the S-wave DD*2 state with I(JP) = 0(2-) are the possible doubly charmed molecular tetraquark candidates. With the accumulation of experimental data at Run III and after a High-Luminosity LHC upgrade, these predicted doubly charmed molecular tetraquark states can be accessible at LHCb in the near future.
