J. Sollfrank et U. Heinz, CHIRAL AND GLUON CONDENSATES AT FINITE-TEMPERATURE, Zeitschrift fur Physik. C, Particles and fields, 65(1), 1995, pp. 111-121
We investigate the thermal behaviour of gluon and chiral condensates w
ithin an effective Lagrangian of pseudoscalar mesons coupled to a scal
ar glueball. This Lagrangian mimics the scale and chiral symmetries of
QCD.
