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- γ* D 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- e+e-γγ e+e-D D +X and the process of monophotonic e+e--annihilation yield comparable numbers of the charmed meson pairs.
