Subject: The Cathedral Builder's Paradigm' or `Studies of Heavy Flavour Dynamics: Its Glorious Past and Equally Promising Future
Refreshments served in Room 216 Physics after colloquium

The discovery of CP Violation in kaon decays 1964 created quite a shock in the HEP community despite the fact that parity violation had been established a few years earlier. The impact of this discovery can be illustrated by the very peculiar theory that had been suggested for it: the KM ansatz seemed a priori unlikely to be correct. Yet since the turn of the Millenium it has been empirically validated in the decays of B mesons to an impressive degree -- while failing to provide a scenario for baryogenesis. This success of the Standard Model of HEP does not invalidate the experimental and theoretical arguments for its incompleteness. The task of uncovering the dynamics driving electroweak symmetry breaking provides our
generational challenge. It will be addressed by experiments undertaken at the LHC. A dedicated continuation of comprehensive studies of heavy flavour transitions will be a central element in confronting this challenge.
