Experimental study of the decay
The E391a Collaboration, J. K. Ahn
The first dedicated search for the rare neutral-kaon decay has been carried out in the E391a experiment at the KEK 12-GeV proton synchrotron. The final upper li…
Backward-angle photoproduction of eta meson from protons at E_gamma = 1.6 - 2.4 GeV
M. Sumihama, D. S. Ahn, J. K. Ahn +48
Differential cross sections for eta photoproduction off protons have been measured at E_gamma = 1.6 - 2.4 GeV in the backward direction. A bump structure has been observed above 2.…
Measurement of the incoherent photoproduction near threshold
W. C. Chang, M. Miyabe, T. Nakano +52
We report measurements of differential cross sections and decay asymmetries of incoherent -meson photoproduction from the deuteron at forward angles using linearly polarized pho…
Near-threshold Lambda(1520) production by the gamma p -> K+Lambda(1520) reaction at forward K+ angles
H. Kohri, D. S. Ahn, J. K. Ahn +36
Differential cross sections and photon-beam asymmetries for the gamma p -> K+ Lambda(1520) reaction have been measured with linearly polarized photon beams at energies from the thr…
Near-threshold photoproduction of from protons and deuterons
LEPS Collaboration, N. Muramatsu, J. Y. Chen +53
Photoproduction of (1520) with liquid hydrogen and deuterium targets was examined at photon energies below 2.4 GeV in the SPring-8 LEPS experiment. For the first time, the diffe…
Effects of radiation damage caused by proton irradiation on Multi-Pixel Photon Counters (MPPCs)
T. Matsumura, T. Matsubara, T. Hiraiwa +9
We have investigated the effects caused by proton-induced radiation damage on Multi-Pixel Photon Counter (MPPC), a pixelized photon detector developed by Hamamatsu Photonics. The l…
