Abstract
The calculation of D-wave charmonium production rates in B meson decay s under the NRQCD factorization formalism is presented. We find that t he inclusion of the color-octet contributions permits us to detect the D-wave charmonium states in B decays at present experimental faciliti es. The same amount of signals of the 2(--) D-wave state as that of ps i' could be observed at CERN LEP and CESR. We also predict that the re lative production rates for four D-wave states are delta(c): delta(1)( c) : delta(2)(c): delta(3)(c) = 2.5:3:5:7, where delta(c), delta(1)(c) , delta(2)(c), delta(3)(c) represent, respectively, the 2(-+), 1(--), 2(--), 3(--) states.
