Asymptotic conditions in quantum field theories

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

On the ground of quite general hypotheses, as Lorentz invariance of the theory and causality, and restricting oneself to the case in which no zero-mass particles occur, one proves that it is possible to define in the ordinary field theory « asymptotic states» according toHaag. The proof is mainly based on the integral representations of the generalized singular functions.

Riassunto

Sulla base di ipotesi molto generali, come Lorentz invarianza della teoria e causalità e con la restrizione al caso dell’assenza di particelle di massa nulla, si dimostra che è possibile definire nell’ordinaria teoria di campo « stati asintotici » secondoHaag. La dimostrazione si basa in gran parte sulle rappresentazioni integrali delle funzioni singolari generalizzate.
