英文摘要	Inclusive S- and P-wave charmonium productions in the bottomonium ground state eta(b) decay are calculated at the leading order in the strong coupling constant as and quarkonium internal relative velocity v in the framework of the NRQCD factorization approach. We find the contribution of eta(b) -> x(cj) +gg followed by x(cj) -> J/Psi + y is also very important to inclusive Pip production in the eta(b) decays, which maybe helpful to the investigation of the color-octet mechanism in the inclusive Hip production in the eta(b) decays in the forthcoming LHCb and SuperB. As a complementary work, we also study the inclusive production of eta(c), and x(cj) in the eta(b) decays, which may help us understand the X(3940) and X(3872) states. (C) 2010 Elsevier B.V.
