Abstract

We suggest searching for excited charmonium states in e⁺e^\ensuremath- annihilation via double charmonium production at √(s)=10.6 GeV with B factories, based on a more complete leading order calculation including both QCD and QED contributions for various processes. In particular, for the C=+ states, the \ensuremathχ_c0(nP) (n=2,3) and \ensuremathη_c(mS) (m=3,4) may have appreciable potentials to be observed, while for the C=\ensuremath- states, the \ensuremathη_ch_c production and especially the \ensuremathχ_c1h_c production might provide opportunities for observing the h_c with higher statistics in the future. A brief discussion for the X(3940) observed in the double charmonium production is included.
