Deconfinement in QCD at Finite Temperature
  We present a simple and intuitive picture for the deconfinement of quarks and gluons at finite temperature: as the temperature increases, QCD behaves like QED at T=0. We show this by calculating the QCD coupling constant as a function of the temperature and of the external momenta used to probe quarks and gluons.
