AbstractThe decay behaviors of the Ds+Ds- molecule state have been studied in an effective Lagrangian approach. We find that the Ds+Ds- molecule state dominantly decays into D (D) over bar and eta c eta. The total and partial widths are strongly dependent on the model parameter, however, the ratio of the partial widths for eta c eta and D (D) over bar is relatively stable and predicted to be about 0.17 similar to 0.22. In addition, our evaluation shows that the partial width for the Ds+Ds- molecule to J/psi omega is too small to be observed, thus the charmonium-like state X(3915) should not be a Ds+Ds- molecule state.
