Neutral currents and gauge theories--past, present, and future
J. J. Sakurai · AIP conference proceedings · 1978
It is a pleasure to have this opportunity address a distinguished ayduebce gathered here to celebrate the 50th anniversary of the relativistic wave equation. Anybody who has followed the development of weak interaction physics in the past half century must by now realize that the power of relativistic quantum theory, pioneered by Professor Dirac,1 in making nontrivial predictions is by no means limited to the narrow domain of QED. What is even more striking, theorists nowadays speculate on the unification of weak and electro‐magnetic forces while experimentalists, within the next decade or two will explore the energy regions where weak and electromagnetic effects are bound to be comparable and, in a certain sense, inseparable. In my talk I would like to review our past accomplishments, report on the present status and, at the same time, indicate possible future directions in this fascinating field of neutral currents and gauge theories.
