Exlusive charmed meson pair production

Abstract

The experimental data of BELLE Collaboration on the exclusive charmed meson pair production in the process of monophotonic $e^{+}{e}^{-}$-annihilation ($e^{+}{e}^{-}\to {\gamma }^{\ast }\to D\bar{D}$) has been studied. It has been shown that these data is described satisfactorily in the frame work of constituent quark model. Our studies have demonstrated that the central production process $e^{+}{e}^{-}\to e^{+}{e}^{-}\gamma \gamma \to e^{+}{e}^{-}D\bar{D}+X$ and the process of monophotonic $e^{+}{e}^{-}$-annihilation yield comparable numbers of the charmed meson pairs.
