论文摘要
我们介绍了$ b_s $和$λ_b$ hadrons的半雌性宽度的估计。我们采用了最新的拟合$ b $包含半蛋白质的数据，重型夸克扩展和晶格QCD结果。我们的结果遭受了很大的不确定性，可以通过专用的测量和新的晶格QCD计算来减少。
We present estimates of the semileptonic widths of the $B_s$ and $Λ_b$ hadrons. 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.
