Dilepton production at intermediate energies with in-medium spectral functions of vector mesons

We report on a self-consistent calculation of the in-medium spectral functions of the ρ and ω mesons at finite baryon density. The corresponding in-medium dilepton spectrum is generated and compared with HADES data. We find that an iterative calculation of the vector meson spectral functions provide...

Description
Summary:We report on a self-consistent calculation of the in-medium spectral functions of the ρ and ω mesons at finite baryon density. The corresponding in-medium dilepton spectrum is generated and compared with HADES data. We find that an iterative calculation of the vector meson spectral functions provides a reasonable description of the experimental data.
