| Abstract: | In the framework of the thermo field dynamics (TFD) we discuss thermal production of dileptons in quark gluon plasma (QGP) of finite temperature and density up to the first order of QCD correction. We show that the temperature effect to the thermal production rate is rather different from that of the chemical potential, in fact, they give rise to opposite effects which may influence the observation of the dilepton production in QGP. |
