Summary
We propose a Veneziano-type model for the processes having the correct asymptotic behaviour and spin structure, the right isospin and signature on the parent trajectories and the appropriate factorization properties on the lowest poles. The requirement of a minimum number of satellite terms greatly reduces the number of free parameters.
Riassunto
Si propone un modello del tipo di quello di Veneziano per i processi. Esso ha andamento asintotico e proprietà di spin corretti, spin isotopico e segnatura sulle traiettorie « madri » e le giuste proprietà di fattorizzazione ai poli più bassi. La richiesta che il numero di termini satelliti sia minimo riduce grandemente il numero di parametri liberi.
Реэюме
Мы предлагаем модель типа модели Венециано для процессов Nπ, имеюшую правильное асимптотическое поведение и спиновую структуру, правильный иэоспин и сигнатуру на исходных траекториях и соответствуюшие свойства факториэации в ниэщих полюсах. Требование минимального числа сател-литных членов в эначительной степени сокрашает число свободных параметров.

We do not put other baryon trajectories in the model so as not to over-complicate it.
Contrary to what generally happens in this kind of models, it is possible for us to have the pion and eta particles not degenerate in mass.
