Summary
The thermodynamics of hadron matter is investigated on the basis of the bag model. Starting with a critical discussion of previous studies carried out within the same framework, we show that, by allowing for fluctuations of the bag volume, a first-order phase transition does occur at high temperature, leading to a true deconfined plasma. The behaviour of characteristic physical quantities in the transition region is then worked out and discussed.
Riassunto
Si studia la termodinamica della materia adronica sulla base del modello a sella. Partendo da una discussione critica dei precedenti studi condotti nello stesso ambito si mostra che, ammettendo fluttuazioni del volume della sacca, si verifica una transizione di fase del primo ordine ad alta temperatura, che porta ad un plasma vero non confinato. Si elabora e si discute il comportamento delle quantità fisiche caratteristiche nella regione di transizione.
Резюме
На основе модели «мещка» исследуется термодинамика адронного вешества. Исходя из анализа предыдуших исследований в рамках того же подхода, мы показываем, что, предполагая флуктуации общема «мещка», фазовый переход первого порядка имеет место при высокой температуре, который приводит к неограниченной плазме. Рассматривается поведение характерных физических величин в переходной области.
