First measurement of coherent -meson photoproduction from helium-4 near threshold
LEPS Collaboration, T. Hiraiwa, M. Yosoi +42
The differential cross sections and decay angular distributions for coherent -meson photoproduction from helium-4 have been measured for the first time at forward angles with l…
Beam polarization asymmetries for the p(gamma,K+)Lambda and p(gamma,K+)Sigma0 reactions at Egamma=1.5-2.4 GeV
LEPS Collaboration, R. G. T. Zegers, M. Sumihama +50
Beam polarization asymmetries for the p(gamma,K+)Lambda and p(gamma,K+)sigma0 reactions are measured for the first time for Egamma=1.5-2.4 GeV and 0.6<cos(theta_cm(K+))<1.0 by usin…
Evidence for Narrow S=+1 Baryon Resonance in Photo-production from Neutron
LEPS Collaboration, T. Nakano
The gamma n -> K+ K- n reaction on 12C has been studied by measuring both K+ and K- at forward angles. A sharp baryon resonance peak was observed at 1.54 +- 0.01 GeV with a width s…
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 diff…
