Pions in Matter Matter

The Isospin Quantum Molecular Dynamics Model (IQMD) is used to analyse the properties of pions in heavy ion collisions in the range beyond 2 AGeV. We find a strong rescattering causing the pions to show a signature of rather low freeze out densities even if they are initiated at high densities. The analysis of the pion sideward flow may yield insights into the delta-nucleon interaction. The mass distribution of the final delta does not need a medium mass shift of the pole in order to be understood. The analysis of pion isospin ratios may reveal information on the neutron skin of the nucleus.
