“…All three states appear at a cutoff Λ of about 2 GeV, and variation of the binding energies with cutoff is relatively slower compared with systems with quark configuration [Q q][q s]. Obviously, as discussed in the literature [8][9][10][11][12][13][14][15][16]46], the X 0 (2900) reported by LHCb Collaboration can be related to these states. Considering the spin of X 0 (2900), it should correspond to the 0 + state of D * K * interaction.…”

“…However, some studies disfavor such assignment, such as a study in extended relativized quark model [7]. Since X 0 (2900) is close to the D * K threshold, some authors tended to choose the molecule interpretation [8][9][10][11][12][13][14][15][16]. Within the molecule scheme, the investigations of X 0 (2900) were performed within chiral unitary approach [14], a quark delocalization color screening model [8], a oneboson exchange model [9], QCD sum rule [10,11,13], and an effective Lagrangian approach [15].…”

In this work, we systematically investigate the heavy-strange meson systems, D ( * ) K ( * ) / B( * ) K ( * ) and D( * ) K ( * ) /B ( * ) K ( * ) , to study possible molecules in a quasipotenial Bethe-Salpter equation approach together with the one-boson-exchange model. The potential is achieved with the help of the hidden-gau ge Lagrangians. Molecular states are found from all six S-wave isoscalar interactions of D ( * ) K ( * ) / B( * ) K ( * ) . The charmed-strange mesons D * s0 (2317) and D s1 (2460) can be related to the DK and D * K states with spin parities 0 + and 1 + , respectively. The recent observed B sJ (6158) may be assigned as a BK * molecular state with 1 + . Four molecular states are produced from the interactions of D( * ) K ( * ) /B ( * ) K ( * ) , among which the D * K * molecular state with 0 + can be related to the X 0 (2900). No isovector molecular states are found in the interactions considered. The current results are helpful to understand the internal structure of D * s0 (2317), D s1 (2460), X 0 (2900), and new B sJ states. The experimental research for more heavy-strange meson molecules are suggested.

“…The study of other properties such as production and decay patterns become essential, which are very sensitive to the inner structures of the multi-quark system. There are several theoretical studies about the decays and productions [15,18,22,34,35]. For instance, the authors in Ref.…”

Mass spectrum and strong decays of tetraquark $${\bar{c}}{\bar{s}} qq$$ states

et al. 2021

We systematically study the mass spectrum and strong decays of the S-wave $${\bar{c}}{\bar{s}} q q$$ c ¯ s ¯ q q states in the compact tetraquark scenario with the quark model. The key ingredients of the model are the Coulomb, the linear confinement, and the hyperfine interactions. The hyperfine potential leads to the mixing between different color configurations, and to the large mass splitting between the two ground states with $$I(J^P)=0(0^+)$$ I ( J P ) = 0 ( 0 + ) and $$I(J^P)=1(0^+)$$ I ( J P ) = 1 ( 0 + ) . We calculate their strong decay amplitudes into the $${\bar{D}}^{(*)}K^{(*)}$$ D ¯ ( ∗ ) K ( ∗ ) channels with the wave functions from the mass spectrum calculation and the quark-interchange method. We examine the interpretation of the recently observed $$X_0(2900)$$ X 0 ( 2900 ) as a tetraquark state. The mass and decay width of the $$I(J^P)=1(0^+)$$ I ( J P ) = 1 ( 0 + ) state are $$M=2941$$ M = 2941 MeV and $$\Gamma _X=26.6$$ Γ X = 26.6 MeV, respectively, which indicates that it might be a good candidate for $$X_0(2900)$$ X 0 ( 2900 ) . Meanwhile, we also obtain an isospin partner state $$I(J^P)=0(0^+)$$ I ( J P ) = 0 ( 0 + ) with $$M=2649$$ M = 2649 MeV and $$\Gamma _{X\rightarrow {\bar{D}} K}=48.1$$ Γ X → D ¯ K = 48.1 MeV, respectively. Future experimental search for X(2649) will be very helpful.

Motivated by the discovery of fully open-flavor tetraquark states X0(2900) and X1(2900) by the LHCb Collaboration, the magnetic dipole moment of the X1(2900) state with the quantum numbers J P = 1 − is determined in the diquark-antidiquark model using the light-cone sum rules. The magnetic moments of hadrons encompasses useful knowledge on the distributions of charge and magnetization their inside, which can be used to better understand their geometrical shapes and quark-gluon organizations. The observation of the X0(2900) and X1( 2900) as the first two fully open-flavor multiquark states has opened a new window for investigation of the exotic states. The obtained results in the present study may shed light on the future experimental and theoretical searches on the properties of fully open-flavor multiquark states.
