Abstract:
The production and decay of vector mesons (rho, omega) in p A reactions at COSY energies 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 p-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. The perspectives of scalar meson (f(0), a(0)) production in pp reactions are investigated within a boson-exchange model indicating that the f(0)-meson might hardly be detected in these collisions in the K<($)over bar> or pi pi decay channels whereas the exclusive channel pp --> da(0)(+) looks very promising.
