Summary
We consider the hydrodynamical expansion of hadronic matter of the Landau model for a system governed by the statistical-bootstrap exact equation of state. The main results are the modification of the linear growth of the fireball multiplicity into a slower behaviour and the temperature dependence of the velocity of sound, which gives an idea of the spectrum of collective excitations.
Riassunto
Si considera l’espansione idrodinamica della materia adronica del modello di Landau per un sistema governato dall’esatta equazione di stato di Bootstrap statistico. I risultati principali sono la modificazione della crescita lineare della molteplicità della «fireball» in una più lenta crescita e la dipendenza della velocità del suono dalla temperatura, che dà un’idea dello spettro delle eccitazioni collettive.
Реэюме
Мы рассматриваем гидромагнитное расщирение адронного вешества в модели Ландау для системы, подчиняюшейся точному уравнению состояния статистического бутстрапа. Основные реэультаты работы состоят в следуюшем: получены преобраэование линейного роста множественности файрболов в более медленное поведение и температурная эависимость скорости эвука, которая дает представление о спектре коллективных воэбуждений.
