| Abstrakt: | In order to formulate a satisfactory QFT it is not sufficient to secure renormaliz-ability, but rather superrenormalizability. On the other hand, it is not necessary to search for a formalism completely free of infinities. A Superrenormalizable QED inn⩾4 dimensions may be formulated by introducing a relativistic form factor preserving gauge invariance. This formalism is characterized by a running coupling constant and is asymptotically free. A relation between the bare and the dressed coupling constant is discussed anew. |
