Based on the nonrelativistic QCD factorization formalism, we calculate the bottomonium ground state {eta}{sub b}, inclusive charm decays at the leading order in the strong coupling constant {alpha}{sub s}, and quarkonium internal relative velocity v. The inclusive charm pair production in {eta}{sub b} decay is mainly realized through the {eta}{sub b}{yields}ccg process, where the charm and anticharm quarks then dominantly hadronize into charmed hadrons. The momentum distributions of the final states are presented. In this work, we also calculate the J/{psi} inclusive production rate in the {eta}{sub b} decays, where the color-octet contribution is found to be very important. We expect this study may shed some light on finding {eta}{sub b} or knowing more about its nature.
