Real and virtual photon emission of strongly interacting matter — •Falk Wunderlich and Burkhard Kämpfer — Helmholtz-Zentrum Dresden-Rossendorf, D-01328 Dresden, Germany

We present calculations of the photon emissivity of strongly interacting matter. Within the HTL approximation the resulting spectral function is analyzed to find suitable cuts on the real and virtual photon spectrum in order to obtain a clear signal from the deconfined phase. Emphasis is put on imprints of Van Hove singularities. The analysis is extended to effective theories which describe the chiral or deconfinement phase transition. Here, we search for signals of soft modes nearby a critical point.The work was funded by BMBF.
