英文摘要	Based on the nonrelativistic qcd factorization formalism, we calculate the bottomonium ground state eta(b), inclusive charm decays at the leading order in the strong coupling constant alpha(s), and quarkonium internal relative velocity v. the inclusive charm pair production in eta(b) decay is mainly realized through the eta(b)-> c (c) over barg 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(b) decays, where the color-octet contribution is found to be very important. we expect this study may shed some light on finding eta(b) or knowing more about its nature.
