AbstractTaking the nonspectator contributions from the "tree" level four-quark operators and the penguin-induced operators into account we recalculate the charm number n(c) in B decays. We find that for B- and Lambda(b), penguin contribution can be neglected, while for (B) over bar(d)(0), it is dominant if the nonfactorization factor (t(alpha)t(alpha)) is not sizably large. Some new physics may be needed to meet the present data.
