摘要： The 1/mc and 1/mb corrections to the #3;b → #3;c semileptonic decay are analyzed by QCD sum rules. Within the framework of heavy quark effective theory, the subleading baryonic Isgur-Wise function of #3;b → #3;c has been calculated. It is shown that the corrections due to the 1/m Lagrangian insertion are negligibly small. The sizable 1/mQ effect to the decay lies only in the weak current. The decay spectrum and the branching ratio are given.
