Propagation of broad meson resonances in a BUU type transport model:   Application to di-electron production
  We apply a BUU type transport model for the interpretation of the di-electron invariant mass spectrum measured by the HADES collaboration for the reaction C(2 AGeV) + C. Our model incorporates the propagation of broad meson resonances emerging from the decay of baryon resonances.
