Summary
Meson-nucleon dispersion relations with e.m. correction toe 2 order are proved, and a conjecture about the unphysical range absorptive part is discussed together with a comment about the Chew-Low extrapolation procedure.
Riassunto
In questo lavoro si dimostrano le relazioni di dispersione pione-nucleon includendo le correzioni elettromagnetiche nell’ordine più basso e si discute una ipotesi relativa al calcolo della parte assorbente dell’ampiezza nella regione non fisica dell’energia. In connessione colle proprietà analitiche nella massa della parte assorbente dell’ampiezza, si esamina la congettura di Chew-Low.
