摘要：

Semileptonic decays of heavy flavored hadrons are analyzed in the heavy quark effective theory (HQET) with leading 1/mQ corrections. All existing data for BBAR --> D(*)lnuBAR and DBAR --> K(*)lnuBAR are reproduced well in virtue of 1/mQ corrections, while the value of \Vcb\ derived by the HQET is almost independent of those corrections. In particular, 1/ms corrections are remarkable for DBAR --> K(*)lnuBAR. Semiloptonic decays of LAMBDAc and LAMBDAb are also discussed including the 1/mQ corrections.
