We present estimates of the semileptonic widths of the Bsand Λbhadrons. We employ the latest fit to the B inclusive semileptonic data, the heavy quark expansion and lattice QCD results. Our results suffer from large uncertainties that could be reduced with dedicated measurements and new lattice QCD calculations.

Abstract
We present estimates of the semileptonic widths of the Bsand Λbhadrons. We employ the latest fit to the B inclusive semileptonic data, the heavy quark expansion and lattice QCD results. Our results suffer from large uncertainties that could be reduced with dedicated measurements and new lattice QCD calculations.
