Selfconsistent calculations of mesonic properties at nonzero temperature
Dirk Roder
After a brief introduction on QCD and effective models in the first chapter, I analyze the dependence of the QCD transition temperature on the quark (or pion) mass in the second ch…

Selfconsistent calculations of sigma-meson properties at finite temperature
Dirk Roder
I study the properties of the scalar sigma-meson [also referred to as f_0(600)] at nonzero temperature in the O(N)-model in the framework of the Cornwall-Jackiw-Tomboulis formalism…

The Quark-Mass Dependence of T_C in QCD: Working up from m=0 or down from m=infinity ?
Adrian Dumitru, Dirk Röder, Jörg Ruppert
We analyze the dependence of the QCD transition temperature on the quark (or pion) mass. We find that a linear sigma model, which links the transition to chiral symmetry restoratio…
