英文摘要Very recently the LHCb Collaboration reported the discovery of two open charm tetraquark states, X-0(2866) and X-1(2904). In the present work, we study the D-(*()) and (K) over bar (()*()) interaction in the one-boson exchange model and show that X-0(2866) can be understood as a D*(K) over bar* molecule with I(J(P)) = 0(0(+)), or at least it has a large molecular component. On the other hand, X-1(2904) can not be interpreted as a molecular state. Inspired by the discovery of X-0(2866) and the fact that the D*(K) over bar* interaction is strong enough to generate a bound state, we also discuss the likely existence of other open charm molecules. In the meson-meson sector, two molecules near the mass thresholds of DD* and D*D* with I(J(P)) = 0(1(+)) are obtained, and using the heavy quark flavor symmetry their (B) over bar(B) over bar* and (B) over bar*(B) over bar* counterparts are also predicted. In the meson-baryon sector, seven open charm molecules with I = 1/2 near the mass thresholds of D-(*())Sigma(()(c)*()) naturally appear, as dictated by the heavy quark spin symmetry.
