Particle flow with the HADES detector — •Christina Deveaux for the HADES collaboration — Justus-Liebig-Universität Gießen

The high densities and pressures of the nuclear fireball created in heavy ion collisions modify the momenta of the emitted particles. Particle azimuthal anisotropies (flow) form therefore one of the most sensitive observables to the equation of state of the matter created in such collisions. We studied the flow of protons and pions in Au+Au collisions at 1.23 GeV/u beam energy based on data which was recorded with the High Acceptance Di-Electron Spectrometer (HADES) in 2012. First and preliminary results of the study will be shown and the option to extend the study to the flow of direct photons will be discussed. Supported by BMBF and HICforFAIR.
