Resummation of nonperturbative corrections to the lepton spectrum in inclusive B --> Xl$\overline{\nu}$ decays
We apply the operator product expansion to resum the leading nonperturbative corrections to the endpoint region of the lepton spectrum in inclusive semileptonic $B\to X_q\,\ell\,\bar\nu$ decays, taking into account a finite quark mass $m_q$ in the final state. We show that both for $b\to c$ and $b\t...
