$e^{+}{e}^{-}\to \gamma X(3872)$ near the $D^{\ast }{\bar{D}}^{\ast }$ threshold

Abstract

We evaluate the cross section of the process $e^{+}{e}^{-}\to \gamma X(3872)$ in terms of the content of the $D^{\ast 0}{\bar{D}}^0$ `molecular' component in the wave function of the resonance X(3872). If this component is dominating, the cross section of the reaction $e^{+}{e}^{-}\to \gamma X(3872)$ can reach up to about $10^{-3}$ of that for $e^{+}{e}^{-}\to D^{\ast }{\bar{D}}^{\ast }$ at energy slightly above the $D^{\ast }{\bar{D}}^{\ast }$ threshold, and the considered process can be a realistic source of the X(3872) particles for the studies of this resonance.
