Abstract:
The Brown Muck of Beauty -- The Beauty of the Brown Muck


After a brief introduction into Heavy Quark Expansions (HQE) I discuss their applications to semileptonic decays where one extracts the KM parameters |V(cb)| and |V(ub)| and to total lifetimes of heavy flavour hadrons. If time permits -- and interest by the audience does not wane -- I report on some recent work on quark-hadron duality.
