From QED to the Standard Model

In 1965, the Nobel prize in Physics was given for QED, and 50 years have passed since then. During the last 50 years, we have firmly established the standard model of particle physics, the framework for understanding the four fundamental interactions in nature along with the 12 elementary particles of ‘matter’ and the Higgs boson. In this paper, a review of the essential history of this successful theory is given, and the potential for new physics beyond the standard model is discussed.
