摘要In terms of the heavy chiral unitary approach, the D-s0* (2317), D-s1* (2460) and D-0* (2308) resonances are discussed within the molecular state model. By examining the poles of the full unitary coupled-channel scattering amplitude on appropriate Riemann sheets, the former two states can be well reproduced, but not the third state. If one believes that the third state and first state are corresponding states in the non-strange and strange sectors, respectively, and they are all dominated by the molecular structure, there should exist one wide-width state at about 2.1 GeV and one narrow-width state at about 2.44 GeV, which are associated with the D-0*(2308) state. Meanwhile, we predict possible B-0*(5536) [B-1*(5581)] and B-0*(5819) [B-1*(5877)] states in the non-strange sector as the corresponding states of the strange B-s0* (5725) [B-s1* (5778)] ones.
