Description

In this talk, we discuss inclusive decays of heavy hadrons containing a b-quark, specifically focusing on Lambda-b baryons within the framework of the heavy quark expansion (HQE). By utilising recent lattice QCD calculations of exclusive form factors, we aim to identify the regions in the plane of non-perturbative parameters—namely the kinetic and Darwin terms—that are consistent with small velocity sum rules for the semi-leptonic decays of Lambda-b baryons.
