DESCRIPTION:Speakers: Yoshiki Tanaka (GSI)\nWe are conducting experimental
  search for $\\eta$'-mesic nuclei aiming at investigating in-medium proper
 ties of the $\\eta$' meson. The first experiment was performed in 2014 at 
 GSI by measuring the $^{12}$C($p$\, $d$) reaction near the $\\eta$'-meson 
 production threshold. While no significant peak structure due to the forma
 tion of $\\eta$'-mesic nuclei was observed\, stringent constraints on the 
 formation cross section as well as the $\\eta$'-nucleus interaction have b
 een deduced. As a next step\, we are planning a semi-exclusive measurement
  of the $^{12}$C($d$\, $dp$) reaction to extend the experimental sensitivi
 ty. In addition to the measurement of the ($p$\,$d$) reaction\, a proton e
 mitted from decay of $\\eta$'-mesic nuclei will be identified in order to 
 enhance the signal-to-background ratio in the experimental spectrum. The W
 ASA central detector\, which had been used at COSY\, will be moved to GSI 
 and integrated with the fragment separator FRS to enable the planned semi-
 exclusive measurement. In this contribution\, we will report the present s
 tatus and future plans of this experiment.\n\nhttps://indico.koza.if.uj.ed
