Quark-hadron duality at work: lifetimes of bottom baryons
Abstract In the 1990s, very low experimental values for the lifetime ratio τ(Λ b )/τ(B d ) triggered a considerable amount of doubt in the applicability of the heavy quark expansion (HQE), which is based on the assumption of quark-hadron duality (QHD) for inclusive total decay rates. However, these...
