1/mQ Expansion for Heavy Baryons and Λb->Λclv-Transition in HQEFT
Abstract: The transition matrix elements between heavy baryons each of which contains a single heavy quark are stud-ied in the framework of heavy quark effective field theory. The framework is derived from the full QCD and the heavy quark-antiquark coupling effects are manifestly included in the effective Lagrangian. The transition matrix elements between heavy baryons are expanded up to order . A set of heavy quark spin-flavor independent wave functions are defined to describe these transitions. The form factors and baryon masses are then related to these wave functions. Based on the 1/mQ expansion, we discuss the semileptonic branching fraction of .
