Feasibility study of observing η' mesic nuclei with (p, d) reaction

Abstract

A novel method is proposed to measure η'(958) meson bound states in 11C nuclei by missing mass spectroscopy of the 12C(p, d) reaction near the η' production threshold. It is shown that peak structures will be observed experimentally in an inclusive measurement in case that the in-medium η' mass reduction is sufficiently large and that the decay width of η' mesic states is narrow enough. Such a measurement will be feasible with the intense proton beam supplied by the SIS synchrotron at GSI combined with the good energy resolution of the fragment separator FRS.
