The production and decay of vector mesons () in pA and AA reactions is studied with particular emphasis on their in-medium spectral functions. It is explored within transport calculations if hadronic in-medium decays like
or
might provide complementary information to their dilepton (e
+
e
-) decays. Whereas the
signal from the
-meson is found to be strongly distorted by pion rescattering, the
-meson Dalitz decay to
appears promising even for more heavy nuclei in
and pA reactions. Furthermore, the influence of nucleon and kaon/antikaon potentials on the
yields and spectra in pA collisions is calculated and compared to the recent data from the ANKE Collaboration.
