Abstract:
Recent measurements of the Belle Collaboration of the exclusive production of two charmonia in the annihilation differ substantially from theoretical predictions. Recently it was suggested that a significant part of this discrepancy can be explained by the process and value for its cross-section was published. In this paper it is shown, that these results are incorrect and the values for the cross-sections of the production of different vector charmonia are presented.- electron positron: annihilation
- psi mesons: pair production
- J/psi(3100): pair production
- channel cross section
- differential cross section: angular dependence
- numerical calculations
- interpretation of experiments: KEK TRISTAN Stor
- electron positron --> 2psi mesons
- electron positron --> 2J/psi(3100)
