Abstract
We present a new analysis of double charmonium production in e +e- annihilation. The observation of the processes e + e- → J/ψηc, J/ ψχc0, and J/ψηc(2S) is confirmed using a data set more than 3 times larger than that of Belle's previous report, and no evidence for the process e+e- → J/ψJ/ψ is found. We perform an angular analysis for J/ψηc production and set an upper limit on the production of J/ψJ/ψ. Processes of the type e+e- → ψ(2S)(cc)res have been observed for the first time; their rates are found to be comparable to those of e+e- → J/ψ(cc)res processes.

N2 - We present a new analysis of double charmonium production in e +e- annihilation. The observation of the processes e + e- → J/ψηc, J/ ψχc0, and J/ψηc(2S) is confirmed using a data set more than 3 times larger than that of Belle's previous report, and no evidence for the process e+e- → J/ψJ/ψ is found. We perform an angular analysis for J/ψηc production and set an upper limit on the production of J/ψJ/ψ. Processes of the type e+e- → ψ(2S)(cc)res have been observed for the first time; their rates are found to be comparable to those of e+e- → J/ψ(cc)res processes.
