DYNAMICAL STUDY OF X(3872) AS A D°-D*° MOLECULAR STATE

摘要：

The possibility is considered that X(3872) may be a bound state of D°D*° or D°D*°. By assuming that the short range force between mesons is governed by one-glue-mediated quark exchange between two mesons and long range force by sigma and pion meson exchange, we calculate the binding energy of D°D*⊕ system by solving the Schrodinger equation. Results indicate that there exists a weakly bound S-wave D°D*° state and the binding energy is less sensitive to the parameters of the meson exchange potential.
