Abstract

We present estimates of the semileptonic widths of the BsB_s and Λb\Lambda_b hadrons. We employ the latest fit to the BB 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.
