Bleicher %J Physics %D 2015 %I arXiv %X We calculate dilepton spectra in heavy-ion collisions using a coarse-graining approach to the simulation of the created medium with the UrQMD transport model. This enables the use of dilepton-production rates evaluated in equilibrium quantum-field theory at finite temperatures and chemical potentials. %U http://arxiv.org/abs/1509.05887v1
