Contribution

It presents new experimental data on $ta^{'}$-meson in-medium properties derived from transparency ratio measurements in nuclear matter.

Findings

Quantified the absorption of $ta^{'}$-mesons in nuclei.

Compared in-medium properties of $ta^{'}$, $ta$, and $mbda$ mesons.

Provided experimental constraints on meson-nucleus interactions.

Abstract

The photoproduction of $\eta^{'}$-mesons from different nuclei has been measured using the Crystal Barrel(CB)/TAPS detector system at the ELSA accelerator facility in Bonn. Recent results on the in-medium properties of the $\eta^{'}$-meson, derived from the transparency ratio measurements, are presented. The absorption of the $\eta^{'}$-meson in nuclear matter is compared to the properties of the other mesons ($\eta$ and $\omega$).
