On the Yang-Feldman formalism

  • S. S. Schweber


The connection between the in- and out-fields and the interaction representation fields is established. The commutation rules for these as well as the symmetric field are obtained. The formulation of scattering theory in terms of these fields is rederived from their connection with the interaction representation.


Si stabilisce la relazione tra i campiin eout e il campo della rappresentazione per interazione. Si ottengono le regole di commutazione sia per questi campi che per il campo simmetrico. Dalla loro connessione con la rappresentazione per reazione si deriva nuovamente la formulazione della teoria dello scattering in termini di questi campi.

    M. L. Goldberger has since given a much simpler proof of the dispersion relation. The author wishes to thank ProfessorGoldberger for communicating this proof to him.Google Scholar
