Dilepton production in heavy ion collisions at intermediate energies

We present a unified description of the vector meson and dilepton production in elementary and in heavy ion reactions. The production of vector mesons

is described via the excitation of nuclear resonances R. The theoretical framework is an extended vector meson dominance model (eVMD). The treatment of the resonance decays

with arbitrary spin is covariant and kinematically complete. The eVMD thereby includes excited vector meson states in the transition form factors. This ensures correct asymptotics and provides a unified description of photonic and mesonic decays. The resonance model is successfully applied to the
