The physics of BB factories

Presently at many High Energy Physics laboratories including CORNELL, SLAC, CERN, DESY, KEK and Novosibirsk design studies for a high luminosity 10 GeV e+e− machine are being carried out. This large effort documents a wide consensus in the importance and interest in continued B‐physics. Measurements of the Z0—pole have shown, that there are probably no more than 3 generations of quarks. The t—quark, once found, will immediately decay into a b—quark and will not provide any new information. Thus the b—quark will remain the only tool for precise studies of the weak interaction for ever.
