Abstract
We study <c(c)over bar> color-actet contribution to B --> psi(psi')X. When this contribution is included, the theoretical predictions for th e branching ratios become in much better agreement with the experiment . This mechanism also enhances the partial rate asymmetries by about a factor of five. The inclusive psi(psi') resulting from b --> d + gluo n can have asymmetry around a few percent whereas those from b --> s gluon has it around 4 x 10(-4). The asymmetry in the former modes sho uld be observable, to a significance of 3 sigma, with about (1-10) x 1 0(8)B mesons.
