Charmonium Production in $e^+e^-$ Annihilation at $\sqrt{s}=10.6GeV$

preprint2002arXivOpen access

We review the charmonium production in $e^+e^-$ annihilation at $\sqrt{s}=10.6GeV$ . NRQCD predictions for the $J/ψ$ production are compared with the recent measurements by BaBar and Belle. A NRQCD calculation for the $D$ -wave charmonium production is reported to further test the color-octet mechanism and detect the $J^{PC}=2^{--}$ state. The issue of double $c \bar c$ production in $e^+e^-$ annihilation observed by Belle is also discussed.
