Summary
A dispersion relation and certain analyticity properties of the amplitude for a process like n+π→n′+π′+π″ has been studied on the basis of the Jost-Lehmann-Dyson integral representation of the causal commutator.
Riassunto
Si è studiata una relazione di dispersione e alcune proprietà di analiticità della ampiezza del processo n+π→n′+π′+π″ sulla base della rappresentazione integrale del commutatore causale dovuta a Jost-Lehmann-Dyson.
