“…First, we study the interactions between the charmed-strange meson D * s and the anticharmed-strange mesonD s1 (2536) in the one-bosonexchange (OBE) mechanism, which is often adopted to study the heavy flavored hadrons interactions and identify these observed X/Y/Z /P c states in a hadronic molecular picture [4,5]. Here, we include the contribution from the f 0 (980), η, and φ exchanges for the D * sD s1 system [15]. By considering the heavy quark symmetry, chiral symmetry, and hidden local symmetry [16][17][18][19][20][21], the effective Lagrangians for the (anti-)charmed mesons with the light mesons are constructed as…”

Very recently, the LHCb Collaboration at the Large Hadron Collider at CERN observed new resonance X(4630). The X(4630) is decoded as a charmoniumlike molecule with hidden-strange quantum number well in the one-boson-exchange mechanism. Especially, the study of its hidden-charmed decays explicitly shows the dominant role of $$J/\psi \phi $$ J / ψ ϕ among all allowed hidden-charmed decays of the X(4630), which enforces the conclusion of X(4630) as a charmoniumlike molecule. The discovery of the X(4630) is a crucial step of constructing charmoniumlike molecule zoo.

This work presents an analysis of a hidden charmed pentaquark candidate state with double strange quark in its quark content. The investigation is performed in two parts, which provide the mass prediction of the considered state and its partial decay width for the Pcss → Ξ 0 J/ψ channel. For the analyses, two-point and three-point QCD sum rule methods are applied to get the mass and the width, respectively. The mass for this candidate state is obtained as mP css = 4600 ± 155 MeV with corresponding current coupling constant λP css = (0.81 ± 0.21) × 10 −3 GeV 6 . These results are used in the analysis of the partial width of this state for the decay Pcss → Ξ 0 J/ψ. For this decay, the width is obtained as Γ = 9.52 ± 2.85 MeV. These results may shed light on the future experimental searches in which such types of states are probed and may provide information to discriminate between such possible observations.

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-doublet and the charmed meson (D 1 , D *2 ) in T -doublet 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 * D 1 states with I(J P ) = 0(0 − , 1 − ) and the S -wave D * D * 2 state with I(J P ) = 0(1 − ) should be viewed as the most promising candidates of the doubly-charmed molecular tetraquark states, and the S -wave DD 1 state with I(J P ) = 0(1 − ), the S -wave DD * 2 state with I(J P ) = 0(2 − ), and the S -wave D * D * 2 state with I(J P ) = 0(2 − ) are the possible doubly-charmed molecular tetraquark candidates. With the accumulation of experimental data at Run III and after High-Luminosity-LHC upgrade, these predicted doubly-charmed molecular tetraquark states can be accessible at LHCb in the near future.
