Abstract

The QCD-motivated NJL-model with gluon condensate is studied at finite temperature and baryon number density. We investigate the behaviour of the constituent quark mass, quark condensate, meson masses, F{sub {pi}}, coupling constants g{sub {pi}qq-bar}, g{sub {sigma}qq-bar} and Z as function of temperature T. It is shown that the gluon condensate plays a stabilizing role for behaviour of different physical quantities when temperature changes. 15 refs.; 5 figs.
