In-Medium Properties of the Eta-prime Meson⋆ — •Mariana Nanova — II. Phys. Institut, Universität Giessen
The investigations of in-medium properties of the η′ meson will be presented. The photoproduction of η′ mesons off 12C, 40Ca, 93Nb and 208Pb nuclei has been measured. The experiment was performed at the ELSA accelerator in Bonn with the combined setup of the Crystal Barrel and TAPS detectors. Recent results on the in-medium width of the η′ meson, derived from the transparency ratio measurements, will be presented and compared to results for the ω meson and to theoretical calculations. The absorption of the η′ meson in nuclear matter as a function of its kinetic energy will be discussed.
