DISPERSION THEORY SUM RULES.

SummaryWe have studied dispersion theory sum rules i) forA andB πΞ amplitudes, ii) for the linear combination ofA amplitudes for

Unitary symmetry and superconvergence relations

\pi {\mathcal{N}}

Consistency condition for the inelastic process π−+p→η+n

and πΣ scatterings, and iii) forA andB amplitudes for the process

. When the sum rules are saturated with the low-lying resonances they are found to be reasonably well satisfied.RiassuntoSi sono studiate le regole di somma della teoria di dispersione i) per le ampiezzeA eB di πΞ, ii) per la combinazione lineare delle ampiezzeA per gli scattering
