Abstract: 
We analyze the production of rho-mesons in p + A reactions including both the production by proton-nucleon as well as pion-nucleon collisions within a coupled channel transport approach. The final state interactions of the rho-meson with nucleons are evaluated from a resonance model which allows to extract elastic and inelastic cross sections, We include the latter final state interactions, the rho-meson decay into two pions as well as the final pion-nucleon interactions within the transport approach. We find the invariant mass distribution of pion pairs to be sensitive to the rho-meson properties in the nuclear medium. However, due to the strong final state interactions of pions only light targets like C-12 might be suited to extract a rho-signal from the uncorrelated two pion background which carries information about the in-medium properties of the rho-meson.
