  • D0(2308) and B0 resonances are discussed with the molecular state assumption in the heavy chiral unitary approach. By studying the heavy baryon-pseudoscalar meson interaction, some molecular states are found. It is shown that there exists a bound DK state with a mass of about 2.312±0.041GeV in the strange sector, which can be identified as Ds0(2317). While in the non-strange sector, one wide-width state at about 2.1GeV and one narrow-width state at about 2.44GeV are found. These states should be associated with the D0 state. Therefore, D0(2308) cannot be explained by the assumption of the molecular structure only. Moreover, Bs0 and B0 states are also predicted. A BK bound state with the mass of 5.725±0.039GeV which can be assigned to the Bs0(5725) state and B0(5536) and B0(5819) should be considered as the corresponding states in the non-strange sector.

Abstract: D0(2308) and B0 resonances are discussed with the molecular state assumption in the heavy chiral unitary approach. By studying the heavy baryon-pseudoscalar meson interaction, some molecular states are found. It is shown that there exists a bound DK state with a mass of about 2.312±0.041GeV in the strange sector, which can be identified as Ds0(2317). While in the non-strange sector, one wide-width state at about 2.1GeV and one narrow-width state at about 2.44GeV are found. These states should be associated with the D0 state. Therefore, D0(2308) cannot be explained by the assumption of the molecular structure only. Moreover, Bs0 and B0 states are also predicted. A BK bound state with the mass of 5.725±0.039GeV which can be assigned to the Bs0(5725) state and B0(5536) and B0(5819) should be considered as the corresponding states in the non-strange sector.
