英文摘要 | The new members of the charm-strange family D-sJ*(2317), D-sJ(2460), and D-s(2632), which have the surprising properties, are challenging the present models. Many theoretical interpretations have been devoted to this issue. Most authors suggest that they are not the conventional c (s) over tilde quark model states, but possibly are four-quark states, molecule states, or mixtures of a P-wave c (s) over bar and a four-quark state. In this work, we follow the four-quark-state picture, and study the masses of cn (n) over bar(s) over bar /cs(s)over bar>(s)over bar> states (n is u or d quark) in the chiral SU(3) quark model. The numerical results show that the mass of the mixed four-quark state (cn (n) over bar(s) over bar /cs(s)over bar>(s)over bar>) with spin parity J(P) = 0(+) might not be D-s(2632). At the same time, we also conclude that D-sJ*(2317) and D-sJ(2460) cannot be explained as the pure four-quark state. |
