Abstract: In this paper the processes $e^+ e^- \to J-\Psi J-\Psi, J-\Psi \psi-, \psi-\psi-$ are considered in the framework of light cone formalism. An importantdistinction of this approach in comparison to the approaches used in otherpapers is that relativistic and leading logarithmic radiative corrections tothe cross section can be easily resummed within light cone formalism. In thispaper the effect of this resummation is studied. It is shown that this effectis important especially for the production of higher charmonium mesons. Thepredicted cross sections are in agreement with the upper bounds set by Bellecollaboration.
