We study theoretically the feasibility of the semi-exclusive $^{12}$C($p,dp$)$X$ reaction for the observation of $\eta^\prime$ mesic nuclei using the transport model JAM. The semi-exclusive measurements of the ($p,d$) reaction with protons from $\eta

The γp → pπ0η reaction has been studied with the CBELSA/TAPS detector system to search for experimental evidence for triangle singularities. Kinematically these singularities exist in the decay chain Δ* → ηΔ(1232) → ηπ0 p but do not sho

In the project B.4, the modification of meson properties (mass, width) in a nuclear medium has been studied in photoproduction of mesons off nuclear targets. This work has been motivated by theoretical expectations of in-medium modifications of hadro

We performed a missing-mass spectroscopy experiment of the 12C(p, d) reaction at 2.5 GeV proton energy in order to search for η′ mesic nuclei. An excitation-energy spectrum of 11C was obtained around the η′ production threshold. As no significa

Different experimental approaches to determine the meson-nucleus optical potential are discussed. The experiments have been performed with the Crystal Barrel/TAPS detector system at the ELSA accelerator in Bonn and the Crystal Ball/TAPS at the MAMI a

In order to investigate a possible mass reduction of an η′ meson at finite density, a series of missing-mass spectroscopy experiments of η′-nucleus bound states with the 12C(p,d) reaction is planned at GSI and FAIR. A semi-exclusive measurement

We plan a missing-mass spectroscopy experiment of η′ mesic nuclei with the 12C(p,d)η′⊗11C reaction to study in-medium properties of the η′ meson. In nuclear medium, due to restoration of chiral symmetry, the mass of the η′ meson may be

The η′ meson mass may be reduced due to partial restoration of chiral symmetry. If this is the case, an η′-nucleus system may form a nuclear bound state.We plan to carry out a missing-mass spectroscopy experiment with the 12C(p,d) reaction at G

Investigations of in-medium properties of the η′-meson are presented. The photoproduction of η′-mesons off 12C, 40Ca, 93Nb and 208Pb nuclei has been measured with the Crystal Barrel/TAPS detector system at the ELSA accelerator in Bonn. Comparin
