Flavor Mixing in Weak Interactions, 1984 Physical Sciences Series

The 50-year history of weak interaction since Fermi's pro­ posal of this coupling has been marked with striking direct inter­ plays between experimental results and theoretical understanding, e.g. the discoveries of neutrinos, parity violation, and CP vio­ lation. The recent discoveries of the quark hierarchy, the charm and the beauty, and the intermediate vector bosons W± and ZO have truly made a splendid page in the history of particle physics. It is the purpose of this conference to discuss the questions of quark and lepton generations and mixing, their relations to CP violation, and to ask the questions about what are inside the quarks and the leptons in view of the present and future exper­ imental situation.
