Description
Photons, as all electromagnetic probes, can give direct access to the
hot and dense phase of a heavy-ion reaction. We show calculations of
direct photon emission at SiS100- and SiS-300 energies with the
UrQMD-hybrid model. UrQMD is a full microscopic+macroscopic
transport/fluiddynamics hybrid model with hadron- and string-driven
equilibration phase, a full (3+1)-dimensional fluiddynamic hot and dense
phase and a hadronic after-burner. Unequilibrated matter at high
rapidity is preserved during the fluid phase. A strong emphasis is set
on the impact of viscosity and Equation of State at zero and non-zero
baryon density to the spectra and flow patterns of thermal
and non-thermal photons in A+A-collisions at the colliding systems
relevant for FAIR.
