The processes $e^+ e^- o J/ \Psi \chi_{c0}, \Psi(2S) \chi_{c0}$ at $\sqrt s = 10.6$GeV in the framework of light cone formalism

摘要

In this paper we have analyzed the production of pair charmonium mesons inthe reactions $e^+ e^- \to J/ \Psi \chi_{c0}, e^+ e^-\to \Psi(2S) \chi_{c0}$ atenergy $\sqrt s = 10.6$GeV in the framework of the light cone formalism. Incomparison with NRQCD the numerical results for the cross sections are inbetter agreement with experiment.
