ABSTRACT We present dilepton spectra from p+p and p+Nb collisions at a kinetic beam
energy of 3.5 GeV, which were simulated with the GiBUU transport model assuming
different in-medium scenarios. We compare these spectra to preliminary HADES
data and show that GiBUU can describe the data reasonably well. Our simulations
indicate that the intermediate dilepton-mass region is sensitive to the N-Delta
electromagnetic transition form factor, which up to now is unmeasured in the
time-like region.
