  • SummaryThe Mandelstam representation is proved in each finite order in perturbation theory for processes for which forward scattering dispersion relations have been proved. A continuation in the external masses is then made so that the proof is extended to all processes for which there is no anomalous threshold in lowest order.RiassuntoSi dimostra la validità della rappresentazione di Mandelstam in ogni ordine finito nella teoria di perturbazione per processi pei quali sono state dimostrate… CONTINUE READING
