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/Psi X-c0,e(+)e(-) -> Psi(2S)X-c0 at energy root s = 10.6 GeV 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. (c) 2006 Elsevier B.V. All rights reserved.
