The processes e+e−→J/Ψχc0,Ψ(2S)χc0 at s=10.6 GeV in the framework of light cone formalism

In this Letter we have analyzed the production of pair charmonium mesons in the reactions e+e−→J/Ψχc0, e+e−→Ψ(2S)χc0 at energy s=10.6GeV in the framework of the light cone formalism. In comparison with NRQCD the numerical results for the cross sections are in better agreement with experiment.
