    "abstract": "We analyze the production of $\\rho$-mesons in $p + A$ reactions including\nboth the production by proton-nucleon as well as pion-nucleon collisions within\na coupled channel transport approach. The final state interactions of the\n$\\rho$-meson with nucleons are evaluated from a resonance model which allows to\nextract elastic and inelastic cross sections. We include the latter final state\ninteractions, the $\\rho$-meson decay into two pions as well as the final\npion-nucleon interactions within the transport approach. We find the invariant\nmass distribution of pion pairs to be sensitive to the $\\rho$-meson properties\nin the nuclear medium. However, due to the strong final state interactions of\npions only light targets like $^{12}C$ might be suited to extract a\n$\\rho$-signal from the uncorrelated two pion background which carries\ninformation about the in-medium properties of the $\\rho$-meson.",
