LATTICE QCD AT FINITE TEMPERATURE

摘要

After a brief introduction into basic aspects of the formulation of lattice regularized QCD at finite temperature and density we discuss our current understanding of the QCD phase diagram at finite temperature, present results on the QCD equation of state, the transition temperature and the heavy quark free energy. Furthermore, we discuss in-medium properties of hadrons and present first results from a calculation of thermal dilepton rates resulting from quark anti-quark annihilation in the QCD plasma phase.
