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…

Comprehensive measurement of $η^{'}$ photoproduction off the proton at $E_{γ} < 2.4$ $GeV$

N. Muramatsu, J. K. Ahn, W. C. Chang +61

For the spectroscopy of nucleon resonances at the total energies from the $η^{'}$ -meson production threshold to $2.32$ $GeV$ , photon beam asymmetries of the reaction $γ…

Differential cross sections and photon beam asymmetries of $η$ photoproduction on the proton at $E_{γ}$ = 1.3-2.4 GeV

T. Hashimoto, T. Nam, N. Muramatsu +57

We have carried out exclusive measurements for the photoproduction of an $η$ meson from a proton target with an egg-shaped calorimeter made of BGO crystals (BGOegg) and forward cha…
