In-medium Properties of η' Meson
arXiv:1111.6006 · doi:10.1016/j.ppnp.2012.01.004
Abstract
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' -> π^0π^0η. 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, ω).
