Missing Mass Spectroscopy of η′ Mesic Nuclei with the (p,d) Reaction at GSI

We plan a missing-mass spectroscopy experiment of 0 mesic nuclei with the 12 C(p,d) 0 11 C reaction to study in-medium properties of the 0 meson. In nuclear medium, due to restoration of chiral symmetry, the mass of the 0 meson may be reduced, and 0 bound states in a nucleus may exist. The experiment will be started at GSI with a 2.5 GeV proton beam using FRS as a spectrometer and will be continued at Super-FRS at FAIR. The plan of the experiment and development of a Cherenkov detector and an optics mode are described.
