Abstract: (Oxford Journals)

Semileptonic decays of heavy flavored hadrons are analyzed in the heavy quark effective theory (HQET) with leading 1/m_Q corrections. All existing data for B →D^(*)lν and D →K^(*)lν are re-produced well in virtue of 1/m_Q corrections, while the value of |V_cb| derived by the HQET is almost independent of those corrections. In particular, 1/m_s corrections are remarkable for D →K^(*)lν. Semiloptonic decays of Λ_c and Λ_b are also discussed including the 1/m_Q corrections.
