Excited charmonium mesons production in e+e- annihilation at s=10.6 GeV
Abstract
In this paper the production of excited vector and pseudoscalar charmonium mesons in annihilation is analyzed in the framework of light cone. In particular the cross sections (2S)ηc(1S), (1S)ηc(2S),(2S)ηc(2S) have been calculated. It is shown, that contrary to NRQCD the cross sections calculated in the framework of light cone agree with experimental data.
