e^+ e^- Annihilation into J/psi + J/psi
read the original abstract
Recent measurements by the Belle Collaboration of the exclusive production of two charmonia in e^+ e^- annihilation differ substantially from theoretical predictions. We suggest that a significant part of the discrepancy can be explained by the process e^+ e^- -> J/psi + J/psi. Because the J/psi + J/psi production process can proceed through fragmentation of two virtual photons into two cc-bar pairs, its cross section may be larger than that for J/psi +eta_c by about a factor 1.8, in spite of a suppression factor alpha^2/alpha_s^2 that is associated with the QED and QCD coupling constants.

Exclusive production of P-wave charmonia through two virtual photons in electron-positron annihilation
BSE-CIA calculations give LO cross sections of order 10^{-3} fb for e+e- → χ_c1+η_c and h_c+h_c at 10.6 GeV, with a wave-function-driven hierarchy and power-law falloff.
