英文摘要 | D-0*(2308) and B-0* 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 D (s0)*(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 D-0* state. Therefore, Do*(2308) cannot be explained by the assumption of the molecular structure only. Moreover, B-s0* and B-0* states are also predicted. A B(K) over bar bound state with the mass of 5.725 +/- 0.039GeV which can be assigned to the B-s0*(5725) state and B-0*(5536) and B-0*(5819) should be considered as the corresponding states in the non-strange sector. |
