Summary
Physical content is given to a multiparticle decay scheme of a fireball into pions and/or clusters of pions which was developed previously. Energy-momentum conservation coupled to the assumption of a sequential decay mode leads to a set of dynamical equations directly for physical quantities.
Riassunto
Si dà contenuto fisico ad uno schema sviluppato in precedenza per il decadimento di una fireball in pioni e/o in aggregati pionici. Il decadimento sequenziale che insieme alla conservazione dell’energia-impulso è alla base del modello è formulato in termini di equazioni dinamiche direttamente per grandezze fisiche.
Реэюме
Предлагается фиэическая интерпретация схемы многочастичного распада файербола на пионы или кластеры или на пионы и кластеры одновременно, которая была рассмотрена ранее. Сохранение знергии-импульса, свяэанное с предположением моды последовательного распада, приводит к системе динамических уравнений непосредственно для фиэических величин.

An equation whose structure is similar to eq. (3.6) has been already derived, in a different context, byR. Jengo, A. Krzywicki andB. Petersson:Nucl. Phys.,65 B, 319 (1973). The same can be said about eq. (3.3), which has been derived by the previous authors and byJ. Finkelstein andR. Peccei:Phys. Rev. D,6, 2606 (1972), and about eq. (3.2), which has been derived by them and byI. Montvay:Nucl. Phys.,53 B, 521 (1973). In our approach, however, conservation probability being properly taken into account through eq. (2.1), no arbitrary freedom is associated to the inhomogeneous term in eq. (3.2), which is normalized to unity by the previous authors. This difference, which we believe to be fundamental, reflects also on eqs. (3.6) and (3.3).
