QCD analysis of inclusive B decay into charmonium -: art. no. 054003

We compute the decay rates and H-energy distributions of B mesons into the final state H+X, where H can be any one of the S-wave or P-wave charmonia, at next-to-leading order in the strong coupling. We fmd that a significant fraction of the observed J/psi,psi' and chi(c) must be produced through c (c) over bar pairs in a color octet state and should therefore be accompanied by more than one light hadron. At the same time we obtain stringent constraints on some of the long-distance parameters for color octet production. [S0556-2821(99)01003-6].
