Recent experiments studying the meson-nucleus interaction to extract meson-nucleus potentials are reviewed. The real part of the potentials quantifies whether the interaction is attractive or repulsive while the imaginary part describes the meson absorption in nuclei. The review is focused on mesons which are sufficiently long-lived to potentially form meson-nucleus quasi-bound states. The presentation is confined to meson production off nuclei in photon-, pion-, proton-, and lightion induced reactions and heavy-ion collisions at energies near the production threshold. Tools to extract the potential parameters are presented. In most cases, the real part of the potential is determined by comparing measured meson momentum distributions or excitation functions with collision model or transport model calculations. The imaginary part is extracted from transparency ratio measurements. Results on K + , K 0 , K − , η, η , ω, and φ mesons are presented and compared with theoretical predictions. The interaction of K + and K 0 mesons with nuclei is found to be weakly repulsive, while the K − , η, η , ω and φ meson-nucleus potentials are attractive, however, with widely different strengths. Because of meson absorption in the nuclear medium the imaginary parts of the meson-nucleus potentials are all negative, again with a large spread. An outlook on planned experiments in the charm sector is given. In view of the determined potential parameters, the criteria and chances for experimentally observing meson-nucleus quasi-bound states are discussed. The most promising candidates appear to be the η and η mesons.

“…There have been numerous missing-mass measurements of the differential cross section for the pd → 3 He η reaction away from threshold at COSY [291,292,293,294] and these have confirmed the striking angular dependence illustrated at two energies by the WASA data shown in Fig. 86.…”
