摘要：
I review the status of "good diquarks" in light-quark hadronic structure and argue that the heavy-light diquarks play no role in the structure of b-containing hadrons (including exotics), and their role in b-containing hadrons is likely to be minimal if at all. I explain that a crucial phenomenological proof can be obtained from weak decays of b-containing hadrons, such Lambda(b).
