Photoproduction of η ′ mesons off nuclei and their properties in the nuclear medium
We study the photoproduction of $\eta^\prime$ mesons from nuclei near the threshold within the collision model based on the nuclear spectral function. The model takes properly into account both primary photon-nucleon and secondary pion-nucleon $\eta^\prime$ production processes as well as the effect of the nuclear $\eta^\prime$ mean-field potential on these processes. We find that the secondary pion-induced reaction channel ${\pi}N \to...
