    "abstract": "We discuss the possibility to study the in-medium changes of the properties\nof the omega meson in reactions on ordinary nuclei with elementary\nelectromagnetic probes. We present a tree-level calculation of the elementary\ngamma p -\u003e omega p process which is extended to describe also the\nphotoproduction of medium-modified omega mesons in nuclear matter. Using a\nsemi-classical transport approach we obtain results for e+e- and pi0 gamma\nphotoproduction off heavy nuclei in the invariant mass range of the rho and\nomega mesons. Both reactions are also studied experimentally and are presently\nbeing analyzed at accelerator facilities in Bonn and at Jefferson Lab. We show\nthat the in-medium signals expected can be as large as those obtained in\nheavy-ion reactions.",
