Probing nuclear expansion dynamics with ${\pi }^{-}/{\pi }^{+}$-spectra

S. Teis, W. Cassing, M. Effenberger +3

We study the dynamics of charged pions in the nuclear medium via the ratio of differential ${\pi }^{-}$- and ${\pi }^{+}$-spectra in a coupled-channel BUU (CBUU) approach. The relative energy sh…
