摘要：
We have explored the bound state problem and the scattering problem of the D (D) over bar pair in a meson exchange model. When considering their production in the e(+)e(-) process, we included the D (D) over bar rescattering effect. Although it is difficult to answer whether the S-wave D (D) over bar bound state exists or not from the binding energies and the phase shifts, one may get an upper limit of the binding energy from the production of the B (B) over bar, the bottom analog of D (D) over bar.
