Description
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, as the life time of the compressed stage is too short.
