Talk at ECT* Workshop New perspectives on Photons and Dileptons in Ultrarelativistic Heavy-Ion Collisions at RHIC and LHC 4. December, 2015P. Gubler and K. Ohtani, Phys. Rev. D 90, 094002 (2014). P. Gubler and W. Weise, Phys. Lett. B 751, 396 (2015). Collaborators:Keisuke Ohtani (Tokyo Tech) Wolfram Weise (ECT*, TUM)Introduction mesonm = 1019 MeV
