Query: Modelling the QCD Phase Transition with an Effective Lagrangian of Light
  and Massive Hadrons   The temperature dependence of quark and gluon condensates in QCD as precursor
of the chiral and deconfining phase transition is modelled with a conformally
extended non-linear sigma-model including broken chiral and scale invariance.
The model is further enlarged by including (free) heavier hadrons. Within this
frame we then study the interplay of QCD scale breaking effects and heavier
hadrons in chiral symmetry restoration.
