Expansion for quantum perturbations in random spin systems
C. Itoi, K. Horie, H. Shimajiri +1
Energy eigenstates in the random transverse field Edwards-Anderson (EA) model and the random bond quantum Heisenberg XYZ model in a -dimensional finite cubic lattice are obtaine…
Measurement of Spin-Density Matrix Elements for -Meson Photoproduction from Protons and Deuterons Near Threshold
W. C. Chang, D. S. Ahn, J. K. Ahn +53
The LEPS/SPring-8 experiment made a comprehensive measurement of the spin-density matrix elements for , and at forward production angles.…
Search for bound state via reaction at GeV
A. O. Tokiyasu, M. Niiyama, J. D. Parker +69
A search for bound state (the lightest kaonic nucleus) has been performed using the reaction at E=1.5-2.4 GeV at LEPS/SPring-8. The d…
New determination of the branching ratio of the structure dependent radiative decay
A. Kobayashi, H. Ito, S. Bianchin +23
The branching ratio of the structure dependent (SD) radiative decay relative to that of the decay including the interna…
Evidence of the Î^+ in the γd \to K^+K^-pn reaction
T. Nakano, N. Muramatsu, D. S. Ahn +53
The γd \to K^+K^-pn reaction has been studied to search for the evidence of the Î^+ by detecting K^+K^- pairs at forward angles. The Fermi-motion corrected nK^+ invariant mass di…
Photoproduction of Lambda(1405) and Sigma^{0}(1385) on the proton at E_γ= 1.5-2.4 GeV
M. Niiyama, H. Fujimura, D. S. Ahn +37
Differential cross sections for and reactions have been measured in the photon energy range from 1.5 to 2.4 GeV and the angular range…
