| Abstract: | It is shown that data of the BELLE Collaboration on the exclusive production of charmedmeson pairs via the one-photon mechanism of e+e? annihilation can be adequately described within the constituent quark model. It is also shown that the cross section for the central production of two D mesons in the process \(e^ + e^ - \to e^ + e^ - \gamma \gamma \to e^ + e^ - D\bar D + X\) is commensurate with the cross section for their production in one-photon annihilation. |
