Abstract.

The production and decay of vector mesons (\(\rho, \omega\)) 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 \(\pi^ + \pi^-\) or \(\pi^0 \gamma\) might provide complementary information to their dilepton (e + e -) decays. Whereas the \(\pi^ + \pi^-\) signal from the \(\rho\)-meson is found to be strongly distorted by pion rescattering, the \(\omega\)-meson Dalitz decay to \(\pi^0 \gamma\) appears promising even for more heavy nuclei in \(\gamma A\) and pA reactions. Furthermore, the influence of nucleon and kaon/antikaon potentials on the \(K^\pm\) yields and spectra in pA collisions is calculated and compared to the recent data from the ANKE Collaboration.
