Direct measurement of the in-medium $η^{'}$ mass spectrum through the $γ γ$ decay channel

Y. Matsumura, N. Muramatsu, T. A. Hashimoto +58

We measured the invariant mass of the $η^{'} (958)$ meson through the $η^{'} \to γ γ$ decay channel to search for possible character change of $η^{'}$ in a nuclear mediu…

Evidence for a $K ˉ N N$ quasi-bound state in the $γ d \to K^{0} Λ p$ reaction

R. Kobayakawa, J. K. Ahn, S. Ajimura +34

The $γ d \to K^{0} Λ p$ reaction has been studied to search for a $K ˉ N N$ quasi-bound state using the LEPS2 solenoid spectrometer at SPring-8. A localized enhancement concentrated…
