Nonperturbative Corrections to the Heavy Lepton Energy Distribution in the Inclusive Decays $H_b\ra τ\barνX.$

Abstract

Nonperturbative corrections up to $m_b^{-2}$ to the heavy lepton energy distributions are investigated in the inclusive semileptonic weak decays of heavy flavors in QCD. In the case of $B$-meson decays, for $b \ra uτ\bnu$ transitions they decrease the decay rate by 6\% of its perturbative value, while for $b \ra cτ\bnu$ they decrease it by 10\%.
