Propagation of vector-meson spectral-functions in a BUU type transport model: Application to di-electron production
Barz, H. W.; Kampfer, B.; Wolf, G.; Zetenyi, M.
The time evolution of vector-meson spectral-functions is studied within a kinetic theory approach. We implement this formalism in a BUU type transport model. Applications focus on rho and omega mesons being important pieces for the interpretation of the di-electron invariant mass spectrum measured by the HADES collaboration for the reaction C + C at 2 AGeV bombarding energy. Since the evolution of the spectral functions is driven by the local density, the in-medium modifications are tiny for small collision systems within this approach.
