Chapter 3. On the Structure of Lepton
泰久 片山, Mituo Taketani · Progress of Theoretical Physics Supplement · 1961
The phenomenological and logical problems for the lepton structure are• considered.The investigations are mainly concentrated on the difference between electron and muon, through the weak phenomena and also the electromagnetic phenomena.The remakable mass difference between both particles is discussed from the standpoint of field theory.Finally a tentative scheme of the interrelation in the lepton family is proposed.
