Summary
The generalization of Thirring's formulation of the Zachariasen model in the presence of a CDD pole is given. The local field operator, describing an interacting CDD particle, is introduced. It is shown that the CDD pole can be interpreted as a particle only if the mass renormalization in the Zachariasen model is finite.
Riassunto
Si espone la generalizzazione della formulazione di Thirring del modello di Zachariasen in presenza di un polo CDD. Si introduce l'operatore di campo locale, che descrive una particella CDD interagente. Si dimostra che si può interpretare il polo CDD come una particella solo se la rinormalizzazione delle masse nel modello di Zachariasen è finita.
Резюме
Приводится обобщение формулировки Тирринга модели Захариазена в присутствии CDD-полюса. Вводится локальный оператор поля, описывающий взаимодействующую CDD-частицу. Показывается, что CDD-полюс может быть интерпретирован, как частица, только если перенормировка массы в модели Захариазена является конечной.

For simplicity we shall assume thatn=1 in (3.1),M 1≡M andf 1≡f. The generalization to arbitrary finiten does not introduce any qualitative difficulties.
We recall that the CDD pole determines the position of the real zero of the scattering amplitude, and the CDD particle is described by a pole term, implied by the presence of such a zero.

The best for the Lagrangian description is the inelasticN/D method of (3), where the input information about inelasticity is given by the ratio αel/αtot.
