On the nonperturbative charm effects in inclusive $B\to X_{c} l\nu$ decays

We address the nonperturbative effects associated with soft charm quarks in inclusive B decays. Such corrections are allowed by the OPE, but have largely escaped attention so far. The related four-quark `double heavy' expectation values of the form <B|\bar{b}c \bar{c}b|B> are computed in...
