Summary

We examine the Schwinger-Dyson equation for the quark propagator determined by the gauge approximation technique extended to finite temperatures using the real-time formalism of Dolan and Jackiw and utilizing the singular gluon propagatorà la Ball-Baker-Zachariasen. We conclude: 1)if the phase transitions do in fact occur, thenT CT F; 2) chiralsymmetry restoration does not, however, take place at finiteT C, within the approximations employed.

Riassunto

Si esamina l’equazione di Schwinger-Dyson per il propagatore di quark determinata dalla tecnica di approssimazione di gauge estesa a temperature finite usando il formalismo a tempo reale di Dolan e Jackiw e utilizzando il propagatore di gluoni singolarià la Ball-Baker-Zachariasen. Si conclude: 1)se le transizioni di fase avvengono veramente, alloraT CT F; 2) il ripristino della simmetria chirale comunque non avviene aT C finito entro le approssimazioni impiegate.

Резюме

Мы исследууем уравнение Швингера-Дайсона для пропагатора кварков, определенного с помощью техники калибровочного приближения, обобщенной на случай конечных температур. Мы используем формализм реального времени и сингулярный глуонный пропагатор Болла-Бекера-Захриазена. Мы показываем: 1) если фазовые переходы, в действительности, происходят, тоT cT F; 2) однако восстановление киральной симметрии при конечной температуреT c не происходит в рамках использованных приближений.
