The energy dependence of the in-medium $\eta N$ cross section evaluated from $\eta$-photoproduction

Abstract

Within the Glauber formalism and a BUU transport model we analyze the $\eta$-photoproduction data from nuclei and evaluate the in-medium $\eta N$ cross section. Our results indicate that the $\eta N$ cross section is almost independent of the $\eta$ energy up to 200 MeV.
