Description
We present transport-model simulations of proton-nucleus and nucleus-nucleus
collisions at SIS energies, primarily focusing on electromagnetic and strange
observables in order to learn about the properties of mesons in a dense nuclear
medium. Dilepton and kaon spectra measured by the HADES detector at GSI are
being confronted with transport simulations obtained with the GiBUU model. In
this way we find indications for a nonzero kaon potential in p+Nb as well as the
need for significant in-medium modifications of the $\rho$ meson's spectral
function in Ar+KCl collisions. Further, we discuss the intricacies of handling
such in-medium effects in a transport approach.
