Two problems in thermal field theoryFRANÇOIS GELIS Brookhaven National Laboratory, Nuclear Theory, Bldg 510A, Upton, NY 11973, USA Abstract. In this talk, I review recent progress made in two areas of thermal field theory. In particular, I discuss various approaches for the calculation of the quark gluon plasma thermodynamical properties, and the problem of its photon production rate. Keywords. Thermal field theory; quark-gluon plasma. Pacs No.11.10.Wx; 12.38.Mh |
