QCD in improved ladder approximation at finite temperature

Research output: Contribution to journalArticlepeer-review


Dynamical chiral symmetry breaking is studied in the improved ladder approximation in QCD. The one- and two-loop contributions lead to a second order phase transition. Temperature dependence of the effective potential, quark condensation, constituent quark mass, pion decay constant and so on is calculated. Critical exponents of the phase transition are also estimated.
