"Ceterum censeo Fabricam Super Saporis esse faciendam" ("Moreover I advise a Super-Flavour Factory has to be built")

英文摘要：

The discovery of $B_d - \bar B_d$ oscillations twenty years ago by the ARGUS collaboration marked a watershed event. It persuaded a significant part of the HEP community that the large time dependent \cp asymmetries predicted for some $B_d$ decays might be within the reach of specially designed experiments. This opened the successful era of the $B$ factories, which has a great future still ahead. After sketching the status of heavy flavour physics I describe why we need to continue a comprehensive heavy flavour program not only for its intrinsic reasons -- it is even mandated as an integral part of the LHC program. Notwithstanding the great success anticipated for the LHCb experiment I explain why a Super-Flavour Factory is an essential complement to the LHC program.
