Abstract

The inclusive S-wave charmonium production rates in B decays are considered using the Bodwin-Braaten-Lepage approach, including the relativistic corrections and the color-octet mechanism suggested as a possible solution to the ψ′ puzzle at the Fermilab Tevatron. We first consider relativistic and radiative corrections to J/ψ → e+e- and J/ψ → light hadrons (LH's), in order to determine two nonperturbative parameters 〈J/ψ|O1(3S1)|J/ψ〉, 〈J/ψ|P1(3S1)|J/ψ〉 in the factorization formulas for these decays. Using these two matrix elements and including the color-octet cc̄(3S1) state contribution, we get a moderate increase in the decay rates for B decays into J/ψ (or ψ′) + X. Our results B(B → J/ψ (or ψ′) + X) = 0.58 (0.23)% for Mb = 5.3 GeV get closer to the recent CLEO data. As a by-product, we prefer a larger decay rate for ηc → LH's compared to the present data.
