显而易见

Opening Address,nergy physics follow the recent development in unifying the world of particles and their interactions. So it was probably no surprise to you that we have chosen this title for our school. Since I personally have become more sceptical against enthusiasm with increasing age (one could also say, the bu

Quarkonia, flavour, c = charm [3] could be added to the hadron spectroscopy by the interpretation of the new particles as c. bound states. It was argued that the new system is nonrelativistic: Charmonium [4]. Whereas the old mesons suffered from the fact that the quarks are extremely relativistic (mass differ

Some Current Issues in Gauge Theories,heory could also explain many problems of strong interactions as well. This led to the present picture where there is a successful theory of the electroweak force and a promising candidate for the theory of the strong interactions. In these lectures I address two main auestions:

Summary,It is indeed a challenge to try to put into perspective particle physics of our days for it is at the same time easy and difficult. It is easy and satisfying because of the tremendous steps forward we have taken during the last years; it is difficult and frustrating because we can easily overshoot o

een a bad choice. The field has so rapidly developed and dis­ coveries are chasing each other that much of the optimism of theory has passed over to e+e- experimentalists. A vast amount of experimental material arose from the simple reaction of e+e- annihilation. I, therefore, have to limit myself t
