Outline of Final Research Achievements

We investigate theoretically the mass reduction of the eta'(958) meson in the nuclear medium. To this end, we have calculated the formation spectra of eta'(958) mesic nuclei by using the missing mass spectroscopy. The heavy mass of the eta'(958) meson is considered to be determined by the UA(1) anomaly and chiral symmetry breaking. In this fiscal period, the experiment at GSI has been performed and we have determined the upper limit of the formation cross section of eta'-mesic nuclei and its possible mass reduction.
