Abstract: We calculate thermodynamic quantities in symmetric nuclear matter within theself-consistent Green-s functions method including three-body forces. Thethermodynamic potential is computed directly from a diagrammatic expansion,implemented with the CD-Bonn and Nijmegen nucleon-nucleon potentials and theUrbana three-body forces. We present results for entropy and pressure up totemperatures of 20 MeV and densities of 0.32 fm^-3. While the pressure issensitive to the inclusion of three-body forces, the entropy is not. Theunstable spinodal region is identified and the critical temperature associatedto the liquid-gas phase transition is determined. When three-body forces areadded we find a strong reduction of the critical temperature, obtaining T c ~12 MeV.
