|Vub| AND |Vcb|, CHARM COUNTING AND LIFETIME DIFFERENCES IN INCLUSIVE BOTTOM HADRON DECAYS

Inclusive bottom hadron decays are analyzed based on the heavy quark effective field theory (HQEFT). Special attentions in this paper are paid to the b→u transitions and nonspectator effects. As a consequence, the CKM quark mixing matrix elements |Vub| and |Vcb| are reliably extracted from the inclusive semileptonic decays B→Xueν and B→Xceν. Various observables, such as the semileptonic branch ratio BSL, the lifetime differences among B-, B0, Bs and Λb hadrons, the charm counting nc, are predicted and found to be consistent with the present experimental data.
