Search for the Pair Production of Dark Particles $X$ with $K_{L}^{0} \to X X$ , $X \to γ γ$

C. Lin, J. K. Ahn, J. M. Choi +39

We present the first search for the pair production of dark particles $X$ via $K_{L}^{0} \to X X$ with $X$ decaying into two photons using the data collected by the KOTO experiment. No s…

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…
