The influence of the neutron skin and the asymmetry energy on the ${\pi }^{-}/{\pi }^{+}$ ratio

C. Hartnack, A. Le Fevre, Y. Leifels +1

We use the Isospin Quantum Molecular Dynamics model (IQMD) to analyze the centrality dependence of the isospin ratio of pions, ${\pi }^{-}/{\pi }^{+}$. We find that the density dependence of the…
