内容説明

The main task of an experimental talk at a theoreticians school should probably be a tempering one. In this respect, e+e- physics may have been 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 to recent results - most of them less than one year old. The paper will be organized as follows: In the first lecture (chapter I and II) I will give - a short introduction to e e machines and cross sections. In particular I will discuss the total cross section an- after a short summary on charm - concentrate on the third generation of auarks and leptons: the heavy lepton T and the T family. In my second lecture the various aspects of event topologies in the DORIS energy range will be discussed, including the T decay. In the third lecture I will then describe the new storage ring PETRA and present first results on QED checks, total cross section, jet structure, and two-photon processes.
