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

Abstract

In this paper we have analyzed the production of pair charmonium mesons in the reactions $e^{+}{e}^{-}\to J/\Psi {\chi }_{c0},e^{+}{e}^{-}\to \Psi (2S){\chi }_{c0}$ at energy $\sqrt{s}=10.6$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.
