We have performed an analysis of the    $$e^+ e^- \rightarrow D^{(*)} {{\bar{D}}}^{(*)}$$e  +    e  -   →   D   (   ∗  )D    ¯(   ∗  )data in the region of the    $$\psi (4040)$$    ψ  (  4040  )and    $$\psi (4160)$$    ψ  (  4160  )resonances which have a substantial overlap and require special care. By using the    $$^3 P_0$$3    P  0model to relate the different    $$D^{(*)} {{\bar{D}}}^{(*)}$$D   (   ∗  )D    ¯(   ∗  )production modes, we make predictions for production of these channels and compare with experiment and other theoretical approaches. As a side  effect we find that these resonances qualify largely as    $$c {{\bar{c}}}$$    c    c    ¯states and the weight of the meson–meson components in the wave function is very small.

Analysis of the $$\psi (4040)$$ and $$\psi (4160)$$ decay into $$D^{(*)} {{\bar{D}}}^{(*)}$$, $$D_s^{(*)}{{\bar{D}}}_s^{(*)}$$
