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

摘要

We report on a self-consistent calculation of the in-medium spectralfunctions of the rho and omega mesons at finite baryon density. Thecorresponding in-medium dilepton spectrum is generated and compared with HADESdata. We find that an iterative calculation of the vector meson spectralfunctions provides a reasonable description of the experimental data.
