In-medium properties of η′ meson

Using the Crystal Barrel(CB)/TAPS detector system at the ELSA accelerator facility in Bonn the η′ photoproduction off nuclei (C, Ca, Nb and Pb) was studied via the hadronic decay channel η′→π0π0η. Recent results on the in-medium properties of the η′-meson, derived from the transparency ratio measurements, are presented. The absorption of the η′-meson in nuclear matter is compared to the properties of other mesons (η and ω).
